I was using polygon streaming, it was fine, but just the past few days, it stopped working. The historical agg from polygon works. The code did not change, sometimes after quite a whiel, it prints error message like. “unknown channel A.TACO (you may need to specify the right data_stream)”. Other times, it just hangs there, nothing happens. Tried to print sth right at the beginning of the async loop, nothing printed. When I try to run it from jupyter notebook, it says sth like the eventloop is already running, but nothing is happening.
I contacted polygon, and was told that they do not recognize the error message. Can anyone suggest a solution to this issue, Thanks a bunch!
