I have a very complicated problem with thunderbird.
The ssl connection to my provider is very slow, like almost 3 minutes slow!
After the almost 3 minutes the connection works.
i tested the connection with openssl like this
openssl s_time -connect imap.soverin.net:993
Result: 1 connections in 267 real seconds
then i tested the connection like this
openssl s_client -crlf -connect imap.soverin.net:993
Result: fine, after a waiting time of almost 3 minutes!
Next test is using ip address instead of domain name
openssl s_client -crlf -connect 185.233.34.144:993
Result: this works instantly, perfect.
but if i do the same on another computer in the same home network there is no delay, it works instantly with all tests.
I i start my computer with a live usb then the same commands that causes delays on my normal install work instantly on the live version. No problems on the live boot.
So my conclusion is that somehow the execution is delayed by almost 3 minutes, the big question is where/how?
my install and thunderbird worked fine for years, no firewall installed, standard xfce desktop. all other connections work fine, firefox works fine.
I tried with a new thunderbird profile, same problem.
if anyone has any ideas please do as i’m out of ideas myself
