I've found one discussion using simply 10053. This had nothing to do with my issue. I've been using ver. 6.21 for years. For the last, say 6 months, I will get disconnected just out of the blue and this 10053 code came up in the status window. I started believing it was due to an old version so, I upgraded to 6.43 (new install, all new settings, etc.). It still happened so, I did the latest update to 7.55. Still does it. Not as often but, it is still happening and getting a bit annoying.
Any suggestions or a solution would be greatly appreciated.
