I updated with apt-get update and apt-get upgrade my Ubuntu 14.04 server. I upgraded this packages libgnutls-openssl27:amd64 (2.12.23-12ubuntu2.6, 2.12.23-12ubuntu2.7), multiarch-support:amd64 (2.19-0ubuntu6.9, 2.19-0ubuntu6.10), libfreetype6:amd64 (2.5.2-1ubuntu2.5, 2.5.2-1ubuntu2.6), libc-dev-bin:amd64 (2.19-0ubuntu6.9, 2.19-0ubuntu6.10), libc-bin:amd64(2.19-0ubuntu6.9, 2.19-0ubuntu6.10), libc6:amd64 (2.19-0ubuntu6.9, 2.19-0ubuntu6.10), libgnutls26:amd64 (2.12.23-12ubuntu2.6, 2.12.23-12ubuntu2.7), libc6-dev:amd64 (2.19-0ubuntu6.9, 2.19-0ubuntu6.10) Now I can't login into roundcube. connection to the IMAP server failed. On mozilla firefox I can't even acces the login site. SEC_ERROR_OCSP_TRY_SERVER_LATER The apache error log is full of [ssl:error] [pid 32121] (EAI 2)Name or service not known: [client 89.212.21.92:1880] AH01972: could not resolve address of OCSP responder
I found this for the error message: https://www.liquidweb.com/kb/error-sec_error_ocsp_try_server_later-solved/ It is about whm but it's worth a try to see if this solves the problem. Edit the /etc/apache2/sites-available/ispconfig.conf file and add the lines: SSLUseStapling on SSLStaplingCache shmcb:/tmp/stapling_cache(128000) then restart apache.
Till you are again a life saver! After adding those two lines at the bottom and restarting, everything started working. THANKS!
hahaha... after todays update brought teh same problem. But this time you have to comment out those two lines and restart apache and it works!
