Hello,
so far I havent found any usefull information do get Opera accessing again my router via 192.168.1.1
I get the following message (in german) to be seen in the picture.
I can access without any issues via Microsoft Edge.
I checked if I have the latest version and it is 92.0.4561.43
I don't know since when I have this issues as most people never access their router once it has been set up, but I think that I am sure that in this year (2022) it still worked as from time to time my printer does some shenanigans.
