According to Sandro my forum " DNS over HTTPS not working Nov-26-2019" was closed because I did not respond. I though a forum remained open for 30 days. Below is the response from Sandro
“This thread was set to auto-close as you did not react to any responses and questions any more. It has been reopened now but if you want a discussion you need to react to what people write, so please address the previous questions and act on what has been suggested so far.”
How quickly should a forum member respond before a ticket be closed?
