Mycroft RH

I have been using BBO for some time including tournaments. Recently I lose the connection approx 30 seconds after logging on to BBO. This happens on multiple android devices and both chrome and edge browser (I logged on via edge for the first time specifically to test this and the connection dropped in the first 30 seconds). I can log on using a phone connection with wifi turned off. I have done a reset on the modem to no avail.
