I have multiple accounts in Yahoo, Zoho, GMX, and AOL, and PopMan checks them all. Today, I got timeouts on all of them. Here is an example:
I tried decreasing the check frequency (it has given me timeouts in the past) but that didn't make any difference. I restarted my router to get a new IP but still email@example.com: Connection failure (Unable to connect to "imap.mail.yahoo.com" [Timeout]); ErrCode: 1401
I launched Thunderbird and I was able to login to all of them, and read new mail that some of the accounts had received.
I though that there was something with the settings so I deleted the ini file and started fresh, adding only one account. But that didn't helped either.
So... Is there anything else I can try?
