Yes you are correct. This is the only reason for me from last a few days I am not regularly online after coming back from hospital. I really don't feel comfortable to use a VPN which I am using now :-(
Do you still have the same issue? I remember trying to access the forum using a regular browser and I was not able to access the forum due to Cloudflare verifications. So, when I saw your thread, I was saying to myself that it was not only you and not only for Tor users. Some other users also had the same issue. I just tried Tor to access the forum and it worked well.
BTW, are you feeling good now? Sorry, I didn't know you were sick.
