Hi,
Using an Apple iMac and Chrome, Safari or Firefox, for the past two days I've been unable to log-in to my RoundCube email.
When using the shortcut, no log-in appears on the screen, just a non-stop connection attempt.
When actually able to get to a log-in screen using correct name and password, it just reports "log-in failed"
A friend can access the account from a PC.
Has there been some recent upgrade which has prevented Apple iMac from using RoundCube?
I think it's not RC problem. May be problem with your network or your mail server
Try open from mobile or another wifi.
