Just wild guess.
Student can connect via the mobile network but not through the ISP
router?
Might that be the port for ssh on the router ?

Hello Mick,

Thanks for the interest.

Yes, student can connect via mobile.

And, somewhat "yes", student can kind of connect via ISP. It is not that
the port is blocking traffic.
The fingerprint appears, and if accepted the wrong one, the password is
asked for.

But then, of course, the connection fail.

Also, he was able to connect the day before. So whatever it is, it is
recent, and just for one single student.

Also, I asked him to check the router port 22 if it was ok. He did a hard
reset (factory reset) on it. He took a look and it is open.


Is this Putty or something with keys on student's PC ?
If worked before maybe something went wrong with the saved connection but that doesn't explain why cannot connect via phone>router WIFI unless there is separate issue there. I guess I would try connect via command line with verbosity but I'd have to look up exactly the syntax.
