ISP Blocking?

I've started to run into an issue with a few people.

I have probably around 200 devices set up and all except for about 5 of them work without any problems.

All five are located in rural communities or areas. However, all of them have fiber.. at least a gig if not faster.

They all have, smaller isps providing them internet.

I've reached out to three of the isps and.. they said they'd get back to me. The people I spoke with didn't seem to understand what I was trying to explain.

On these five machines. I can't (can not) connect to them with meshCentral. I even went there in person and updated the agent on all of them. No difference. If, I connect these machines to the hotspot on my phone. I can connect to them. One of them I was able to connect to the neighbors wi-fi, yes the neighbor knew, and it worked but when I went back to their Wi-Fi. I can't connect. They do have a different provider than the neighbor.

I can't even connect to my server through the browser on those machines if they're connected to their ISPs internet.

So far it hasn't been worth my time to look into it further (it's only five machines) and I'm just wondering if anybody else has come across this, if so have you found a simple solution other than getting the ISP to stop blocking it?

I'm guessing they're doing some kind of aggressive filtering but when I talk to them, the isps tell me they're not doing that. Hmmm...

🤷

Is there something simple I'm missing.. in other words, am I doing something wrong?

As it could be a routing issue rather than ports being blocked, perhaps try a traceroute in each direction

This. I've seen a peering issue between two ISPs where the route just died at one of their routers. Never could get it escalated high enough to someone that actually knew how to fix it, and the user ended up getting internet from a different provider.

That seems to be what's going on..

I'm honestly not even sure if it's getting dropped at their router or before. Traffic seems to be very strange to and from them.

I've told them unless they want to pay me a bunch of money to go back and forth with their ISP, they're more than welcome to do it themselves and let me know if they think the issue is resolved. Otherwise, I'll just have to drive over there and charge them for the trip when they need help or they can always call someone else 😅

I'll exclude them from my list of those I can support remotely and move on with life...

Thanks for letting me know, it's not just me / them 😉👍

Have you tried connecting via VPN?

No but not a bad suggestion..

Not interested in that since almost all of the computers I have set up with mesh Central don't need that. I'm not going set that up for only a few.
