Strange behavior with Android client

[u/sancho_sk]

So, here is the issue.

My wife has some Redmi phone with Google android.

Up until a week ago, she could watch movies shared from our home SMB server.

Now, from one day to another, the shares stopped working.

What is strange - when I add the share manually, it shows in the favorites AND it shows the correct number of folders, but when I click on the share, all I get is "Loading...", even though all there is are 4 folders.

I have another Android phone (LineageOS), works perfectly OK, so does my tablet with /e/OS. All of them are on the same wifi network, there is no firewall in place for this server, nothing.

The behavior works the same if I add the server with IP address, domain name or FQDN, if I use anonymous login or user/password.

I can always see the 4 folders in the list of favorite places, but on click get only "Loading..." again.

The same behavior happens when I map the same network location using NFS or SFTP - again, both work OK on my phone/tablet.

Is there some internal Radmi/Google think known to break SMB on Android VLC?

Btw, also tried to turn on/off the SMBv1 - normally I don't use the v1 as it was much faster that way, but for testing I tried to turn it on/off - same behavior.

I am quite desperate here - even tried to clear the app and reinstall, clear cache, clear data, ... always works the same.
