Cannot access 192.168.1.1 via OpenVPN with Bitdefender turned on


Until a few updates ago, it was no problem to access my admin page of my router from the outside via OpenVPN.


Now I get this error message in my browser when I try to access 192.168.1.1:

This page does not work

192.168.1.1.1 has not sent any data.

ERR_EMPTY_RESPONSE



After disabling Bitdefender it is possible to access the admin page.


For the sake of completeness:

Hoping to fix this, I deleted Bitdefender Free completely. I tried a fresh install of Bitdefender Free. Immediately after installation, the access to the admin page did work even with virus protection turned on. Until then Bitdefender had not yet updated. Now that Bitdefender has updated, access to 192.168.1.1 via OpenVPN no longer works.


Access to 192.168.1.1 does work anytime in the local network (without OpenVPN). So it must have something to do with the combination of Bitdefender and OpenVPN, I guess.
