I've enabled VPN in the Settings tab, and the VPN badge stays orange forever. It just says "Connecting..." and the Virtual location dropdown has "Optimal location" only. How do I fix/debug that?
It's Opera 45.0.2552.812 on Ubuntu 14.04.4 LTS (x86_64, Unity)
Related or not, I cannot log into Opera forums site from that computer. It says "auth.opera.com didn't send any data". Other HTTPS sites seem to work
I think I've resolved this using the advice listed here: https://ubuntuforums.org/showthread.php?t=1593587&p=10267762#post10267762
TL/DR: Changed MTU in the network settings from Automatic to 1492
