"pickfirstBalancer: failed to NewSubConn" error on pydio 3.01

linux OS
mysql 8
fresh install with few files added…
this appears in the open terminal window

ERROR: 2021/11/16 13:47:17 pickfirstBalancer: failed to NewSubConn: rpc error: code = Canceled desc = grpc: the client connection is closing

any thoughts on what this error may be from?

Jason

after several days using the new installation and monitoring the “parser” terminal window… I still see this error occasionally. Just wanted to know what it meant.

here is a sample from the parser showing the errors still continuing.
This is a localhost implementation for personal use and its behind a firewall and a VPN … so im not the least worried about security…

I do want to know what the recurring error is though.

Hi jason, we’ve spotted the error on some servers as well. Still investigating, not really straightforward but does not seem to be really impacting for now.
