Hi. I am getting the dreaded server connection timeout on thunderbird. The interesting part is, that it happens only when connected to one specific wifi network. And not all the time - 3 days its ok, than for 1 day, i am getting the error all the time, then it suddently works for some time... I tried all kinds of countermeasures (prolonging the timeout time, disabling antivirus, changing the proxy stettings...). Nothing works. I really have no idea where to continue my investigation... Obviously, the problem has something to do with my wifi configuration, just cant figure out what. Thanks for any suggestions.
