Hi, I use Thunderbird for all my email accounts since ... I don't remember, 10 years? More? Anyway, I absolutely love it but, it's been around 2 days now that I can't check my emails for 2 of my accounts: one is gmail, the other one is a custon domain name. It's always been working great so far. The issue I have is the following: _ I launch Thunderbird _ I click on the "check new mails" button _ nothing happens: there's a message "connected to imap.gmail.com...", but this message never disappears and Thunderbird never finalizes the checking new emails process The issue is the same for my other account, with a custom domain name, but Thunderbird behavior is a bit different: I click ont the "check new emails" buttons and I see "connected to "ssl0.ovh.net", and then, after few seconds, it disappears but no new message is download, although there are new messages on the server. Please note that: _ I can still correctly check my messages on the webmail for both accounts _ evereything was working correctly until 2 to 3 days ago _ I never changed any Thunderbird settings, and any system settings as well: I didn't tweak the firewall or whatever. I really hope you can help me, Thank you all in advance! Kind regards, Tom
