An error occurred while logging in - Connection error
I have had mango running for about 18 months, log in once a week or so and check the solar data it
records, and emails me. Last login, I updated, an now a week later, I realise i cannot log in.
The login screen comes up, but fails with "An error occurred while logging in - Connection error"
$ uname -a Linux mango 4.9.0-12-amd64 #1 SMP Debian 4.9.210-1 (2020-01-20) x86_64 GNU/Linux
I noticed the java install advice has changed to openjdk, so I upgraded, but no luck.
$ java --version openjdk 14 2020-03-17 OpenJDK Runtime Environment AdoptOpenJDK (build 14+36) OpenJDK 64-Bit Server VM AdoptOpenJDK (build 14+36, mixed mode, sharing)
ma.log only has INFO data logged
Starting Mango 3.7.5 with Schema Version: 29
all the processes seem to be running OK

I think the two "TIME_WAIT" lines are my login attempt.
Where can I look for errors / logs that might help resolve the issue.
Well its the next morning here in Australia, and I am at home waiting for the corona virus to get me, so I clicked on the link for my mango install, and firefox did the security warning for a self signed certificate again - strange, then
then the login worked, and up came the screen.

Anyway, any thoughts on what magic happened overnight ?

Check your ma.logs, if this thing is internet facing someone may have been hammering it causing the login to drop out in relation to max non-authenticated attempts being tripped..
