Opera VPN not connecting behind pihole

[Scepterus]

Expected Behaviour:

[latest pihole software, on a rp4. when I try to connect to opera VPN, which would be useful to diagnose which sites are actually down and which are blocked by pihole, it should connect and let me browse bypassing the pihole.]

Actual Behaviour:

[the VPN fails to connect, and I've checked the blocked entries in the query log, all opera related traffic isn't blocked.]

Debug Token:

[hc60hsq21w]

[Scepterus]

never mind. this was not the case. I restarted my pihole yesterday and the VPN would not connect until I disabled pihole temporarily and then it connects like a charm.
so what could this be?

Also, some links send you through several referrers and if one of them is blocked, you may land on a …

yeah, I checked the query log, as I mentioned in the first post. nothing popped up.

Did you live tail the Pi-hole log?
