[POP3] An attempt to connect failed. This could be caused by temporary server unavailability

I can’t receive email with eM Client (but on webmail, I still receive email ok). I try update newest version, reinstall, check account setting. But the program still not resolve. Can Team help me fix it? Thanks so much!

First try disabling your anti-virus and firewall application and see if there is any difference.

If that does not help go to Menu > Tools > Accounts and click on the POP3 tab. Set the port to 995 and the security policy to Use SSL/TLS on special port (legacy)
