Description
The local client "local=tcp://127.0.0.1:65441" CAN connect to "remote=tcp://localhost:9002", but failed during handshake later. my knowledge is limited here. Please advise how can I fix this?
I located the place raising error in comm/core.py:
```
try:
# This would be better, but connections leak if worker is closed quickly
# write, handshake = await asyncio.gather(comm.write(local_info), comm.read())
handshake = await asyncio.wait_for(comm.read(), time_left())
await asyncio.wait_for(comm.write(local_info), time_left())
except Exception as exc:
with suppress(Exception):
await comm.close()
raise IOError(
f"Timed out during handshake while connecting to {addr} after {timeout} s"
) from exc
```
