I am having the same problem, constantly. In the middle of a match, it appears as if I’m connected but all of the sudden I can’t play anything, and within a few seconds a “Network Error” pops up. The only way for me to get out of it is open task manager and shut down MTGA and reopen it. There doesn’t seem to be any specific time when it happens, sometimes my turn, sometimes my opponents turn, sometimes late in a best of 3, sometimes as soon as game 1 starts. This started probably about 2 weeks ago and has been happening frequently since. Needless to say, this is extremely frustrating, please do something about this.
