Hmm, that is kind of unexpected. I imagined that TLS would be the culprit, as I have no such errors on my Windows devices, and they use exactly the same wireless Internet connection.
The government here does indeed censor and block and lot of “stuff”, so this is a very good point, but I would expect to have these errors on all my devices then.
I will re-check my DNS settings, and see if there is any difference. If not, then I will create a new topic about the issue.
