My anki was working just fine, until recently Anki just will not sync. There are no issues with my internet connection, and the sync button has now turned red. It states that the connection has timed out. I have tried to even force sync it, but that’s not working either. PLEASE HELP!! ALL MY CARDS ARE ON ANKI AND I HAVE EXAMS COMING UP!
It is likely either temporary issues with your network provider, or antivirus/firewall software on your machine. If you try on a different wifi network or tethering to your phone, that may help.
