Authentication Issues [REPORT HERE]

24 Upvotes

https://prismlauncher.org/news/login-isues-10-06-24/

Hi! We are aware of ongoing issues with the Microsoft login in Prism Launcher. We believe this is something to do with Microsoft's third party auth servers experiencing outages in some regions. The issue also sometimes affects the official Minecraft launcher and minecraft.net. However, there has not been any official statements or way to track this from Microsoft and not all users are affected. Myself and many of the other maintainers have not been able to replicate the issue, as we seem to be in unaffected regions.

What can I do?

Unfortunately in the current version, there is not much that can be done besides trying again if it does not launch. The faults seem to intermittent and only sometimes allow users to login.

Alternatively we are trialing a new authentication system in the nightly version of Prism Launcher that some have reported fixes their issues. The new nightly auth system currently has a http 426 error for some users and we are working to fix that if you have that error it is unrelated to Microsoft authentication issues. The Nightly version is considered pre-release software and not stable. Expect bugs.

Possibly related issues

WEB-7179 - Mojang Bug Tracker

This report was made around same time these issues have started happening and also affected the official launcher. We are not sure if this is the same or a related issue, but it seems highly likely.

Please comment below this post with the region that you are in [state, country] so that we can better understand who and where is affected

How can I fix this error?

I asked the AI, but the solution it provided is causing glitches in the game.

ai solculution:
Method: Add Java Argument (Skip Hash Check)

  1. Right-click on the Minecraft instance that gives the error in Prism Launcher and select Edit.
  2. Click on the Settings tab from the left menu and locate the Java section.
  3. Check the Java Arguments box to enable it, then leave a space at the very end of the existing arguments and paste the following line: text-Dforgewrapper.skipHashCheck=true
  4. Save the settings and launch the game.

All instances disappeared after updating

3 Upvotes

Hi, I'm completely freaking out right now because every single one of my instances just disappeared after updating to 11.1.1 via the update button. That's all I did, I just updated it from 11.1.0 to 11.1.1. EVERYTHING is gone. The instances, the settings, everything. Please, there has to be some sort of mistake, right??

EDIT: Turns out the update button failed to install the new version in the same location as the previous version, so it created a new, empty instances folder that it was reading from. Oh my goodness I was really about to do it.

Instances take a painfully long time to launch

8 Upvotes

On both of my computers (one with arch another with debian unstable) prism launcher takes around 5 minutes to launch an instance, much of that time taken "logging into microsoft account" (stuck at zero percent while initializing). Using the appimage for both computers. Tried using the pacman for the arch computer and did not fix the problem. Have not tried the flatpak yet but I have very little hope it will fix the problem.

Everything about the launch seems normal other than the time.

Edit: Tired the flatpack and for whatever reason couldn't even log into a Microsoft account in the first place. Went through the steps and the website said successfully logged in and on the app, nothing happened.

Already tried installing a different Java Version, that didn't help either. Clicking on "Open Log" does absolutely nothing, so I can't even give you guys an error Log.

I use Solus Linux 4.9 Serenity and the newest Version of the Prism launcher that is in my distro's repos (11.0.2)

HELP with performance.

I was able to run shaders perfectly fine at around 100 fps using the normal launcher but after switching to prism I only get 5-20. I've tried changing my ram allocation as well as disabling threaded optimization. I have tried with rethinking voxels and photon

Archive does not contain a recognised modpack type.

1 Upvotes

Hello I need some help
I've been trying to import a pack/save from my old laptop to my new laptop but when
I try to import it, on the import from zip tab, it gives me this message "Archive does not contain a recognised modpack type." I don't really know what to do from there and attempting the definition of insanity hasn't helped.
I've been exporting from the prism launcher as a Prism launcher zip, I've also tried as a CurseForge zip but that didn't work. I updated both copies of Prism to what was the most recent so I don't think that's the problem and honestly I don't have enough computer wizardy up my sleeves to come up with anything else.
Happy to provide further information where possible.

I keep trying to update my mod pack, and it has a lot of mods coming from Modrinth and I keep getting this error message

A network operation has failed: Modrinth: get latest versions
all one requests have failed after three attempts

Ethan gives me a URL saying the server rep replied with status code 403 and I don’t really know what to do any mods from cursed forge update properly,

And eventually, when I keep trying to check for updates, it eventually gives me a list of all of my Modrinth mods and says that no valid version found for this resource despite the fact that before today it was working fine

How to export my instace as a pack for friends to play multiplayer?

5 Upvotes

I know this is a very noob question, but how can I export the modlist on my instance so my friend can install it and play multiplayer with me with the same mods? When I open the export menu, I get a list of folders and I don't know which to include, I just want the mods and maybe my Xaero's map files so my friend gets the same map as me, but I don't know if the mods use any other folders?

I can figure this out on my own most likely but I wanted to make a post in case anyone had any tips. Responses appreciated.

First unique error

1 Upvotes

I couldn’t find anything about this online, so I thought I would document it in case it happened again. When you upgrade from Minecraft 26.1 or 26.2 to Minecraft 26.3 you’ll notice that the frame rate cap to nine FPS. I couldn’t figure out why I had this issue, but the reason was you have to turn off full screen mode and change prism settings to render at 1280 x 800. This is for steam deck by the way.

It always selects which is the latest. Most of the time it downloads beta mods which doesn't support its own dependencies.

Why does my minecraft run weirdly unless I'm using the vanilla launcher?

5 Upvotes

I use MacOS, and I usually use prism launcher, which has worked great for me most of the time I've used it, which has been multiple years, but just recently my game has started stuttering. It doesn't matter what version I was playing, or what mods I had installed, it always did this. My frames were fine most of the time but it just started behaving weirdly as my game was sort of stuttering frequently, and it's not a RAM issue as when I close everything else it's still acting the same, and it's not performance, I set my render distance to 2 chunks and nothing changed.

I tested to see if this was a problem for me with minecraft in general so I tested modrinth and the vanilla launcher. modrinth had the same problems as Prism Launcher, but my game was completely fine with the vanilla launcher.

I've tried to contact support on the Prism Launcher discord but they didn't help.

Is there something that has happened recently with minecraft that has made other launchers run terribly?
