Title: cannot access web UI anymore
Post by: Nekromantik on November 06, 2018, 07:07:25 pm
Hi all of a sudden I cannot connect to the web UI of OpnSense.
On both Chrome and Edge I get
"ERR_SSL_VERSION_OR_CIPHER_MISMATCH"
I made no changes  to any opnsense ssl settings.
Running 18.7.6

Same here, same version (18.7.6) on a Qotom Q355 G4. Can still access the unit through SSH though and networking is not affected, only web UI is affected in all browsers. Restarting services or rebooting has no effect.

I'm updating to 18.7.7 through console, hopefully this will solve any issue.

Update: no effect. Can a mod (or skilled user) advice me whether I can fix this issue through console or safely revert to 18.7.5?

Update2: updating to 18.7.7 through console and rebooting did solve the problem eventually. Log and bugreport has been sent.

Update3: aaaand we're back to ERR_SSL_VERSION_OR_CIPHER_MISMATCH. Highly annoying. No clue whatsover what causes this and causes it to be intermittent.

FOUND IT!

Bitdefender has started causing issues with unsigned HTTPS certificates which OPNsens, Ubiquiti and other networking equipment uses. Accidentally found other users on other fora with similar recent issues with other equipment. Uninstalled Bitdefender and the issue was directly gone.

Fucking AV software.
