Also launched GoPortable presubmit suite on these changes: https://github.com/apache/beam/actions/runs/13814130500

That is the suite that was previously failing on new versions of grpc.

grpcio==1.71.0 seems not working well. many tests keep failing: https://github.com/apache/beam/actions/runs/13873590601/job/38823181322?pr=34196

[liferoad]

https://github.com/apache/beam/actions/runs/13814130500/job/38824779287 also keeps failing.

1.71: still timeout for many tests.

note: there may be additional, yet to be studied issue in grpc 1.66.0., the original reason why the upper bound was introduced.
