Could not establish connection to xud. Retrying in 5 seconds.

I brought up a new simnet environment (containers running), but waited for several hours before I created the environment. Once everything was created and I received coins, arby couldn't connect to xud:

2020-06-15 08:38:41.4141 [OpenDEX] warn: Could not establish connection to xud. Retrying in 5 seconds.

Then I restarted the whole environment and arby connected fine.

Same happened when I started xud -b feat/arby on an existing testnet environment:

2020-06-15 12:12:58.5858 [OpenDEX] warn: Could not establish connection to xud. Retrying in 5 seconds.

I think this one should be re-tested @raladev

[raladev]

got it today with 2816c11e87e732a833ab73452f3bbdeee49f9f4a commit. Same case, arby restart fixed the situation.

At this point I'm still not sure what's causing it. It seems to reproduce only in xud-docker environment. If you see it with the newer/latest version please attach full logs for arby container.

You should be able to get full logs for a docker container using: sudo vim $(docker inspect --format='{{.LogPath}}' simnet_arby_1)

[raladev]

got it with last commit. xud_log_stuck_1.log arbylog_no_conn.log
