GRPC resolution is None using Tensorboard 2.3 on GCP Debian 4.19.118-2+deb10u1 (2020-06-07). This occurs when switching to Profile view. The issue happens sporadically, usually after keeping Tensorboard open for a while.
The current code seems to be different, so maybe the issue does not exist on nightly.
