i/o timeout for __consumer_offsets topic

Shortly after starting burrow starts throwing timeout error. I have built burrow just now with the latest code.

{"level":"error","ts":1588667263.4975047,"msg":"consume error","type":"module","coordinator":"consumer","class":"kafka","name":"mycluster","topic":"__consumer_offsets","partition":7,"error":"read tcp 172.17.0.7:44122->10.139.161.76:9093: i/o timeout"}
{"level":"error","ts":1588667263.4975176,"msg":"consume error","type":"module","coordinator":"consumer","class":"kafka","name":"mycluster","topic":"__consumer_offsets","partition":10,"error":"read tcp 172.17.0.7:44122->10.139.161.76:9093: i/o timeout"}

My burrow config:

No source file, test, or entry point is named. Start by reproducing the logged i/o timeout using the supplied Burrow configuration, focusing on the Kafka consumer for the __consumer_offsets topic and the mycluster client profile. Done means identifying the cause and documenting or fixing the consumer timeout behavior.
