x509: SAN dNSName is malformed

[larseggert]

Running the amplificationlimit interop test locally on my Mac, i.e.,

python run.py  -s quic-go -c quic-go -t amplificationlimit

fails with this in the logs:

client  | Using commit: eb1c16bd0eb270036ca04cde8fa034569913d6c7
server  | Using commit: eb1c16bd0eb270036ca04cde8fa034569913d6c7
server  | Running QUIC server.
server  | x509: SAN dNSName is malformed

Any ideas?

Might be related to quic-interop/quic-interop-runner#376.

I can't reproduce this locally:

I'm going to close this issue, since it works both on my machine, and on the interop runner:
