Resolution Note (2022.2.X):
The bug was fixed as part of larger set of changes to the networking library. Unity's version of Mono was updated in 2021.2 so this is no longer a problem in that version. Because this issue only causes an exception to be logged we do not plan on taking the untested fix from 7359 into long term support versions of Unity. So unfortunately we do not plan no fixing this issue in versions earlier than Unity 2021.2.
