I haven't had an issue and I haven't seen that error. Try a different browser. I had difficulty with DTube and found that Chrome worked. I use Firefox, Edge and Chrome.

You can also go to steem.chat #help and ask there. They may have the reason why it is happening to you.

Thanks very much for this response. I'm having similar problems with Minds right now, too. It's so frustrating, nothing like this happened before. Now that I'm finally starting to become more active on these platforms, I run into issues nobody seems to have encountered before.
