Chain sync issues with gameofzoneshub-2

[zmanian]

We are seeing issues with full nodes for gameofzoneshub-2.

Iqlusion has a full node halted at 2299.

We have a report of a full node halted at 2328.

Asking for help from the Interchain Berlin team to debug.

Will update scoring timeline based on feed back from Interchain Berlin.

Also seeing reports of invalid port errors.

[jeelimm]

For invalid port error, the below is our log.

1. We use public sentry node of our own
2. We completed connecting to client and connection, but err(port: invalid port) occurs when we try to create channel.

[sriney-staked]

Same error as @jhernandezb , submitted data directly to @zmanian

[zhangyelong]

I can confirm this issue is related to https://github.com/iqlusioninc/relayer/issues/224, it seems the validators of gameofzoneshub-2 have already lost the capabilities for creating channels, try following steps and you will get height 2328 passed:

gaiad unsafe-reset-all
gaiad start

# stop gaiad before height 2328 and start again
gaiad start

Note this is NOT the solution to get gameofzoneshub-2 working, it's just an evidence to show that the validators have lost the capabilities, and your node will lose the capabilities after restarting too, that is why we can pass height 2328 after restarting the node

[Thunnini]

@zhangyelong I also solved this invalid app hash error in this way like you. But, there seems to be a bug in which the node does not load the state properly after restarting. They lost capabilities and the "transfer" port state. So, I can't make the channel like @jeelimm.

[asmodat]

gaiad unsafe-reset-all
gaiad start

# stop gaiad before height 2328 and start again
gaiad start

Does NOT fix the connectivity issue and also getting invalid port here on the rly

[zhangyelong]

gaiad unsafe-reset-all
gaiad start

# stop gaiad before height 2328 and start again
gaiad start

Does NOT fix the connectivity issue and also getting invalid port here on the rly

Yes, I have said that it is not the solution, it's just an evidence :-) The network has lost the capabilities for creating channels.

[iammelea]

new nodes cant sync. halted on 2329

one node sync before is still working

can't start GoZ in this conditions.

[jjangg96]

gaiad start --halt-height=2000 gaiad start

[joe-bowman]

gaiad start --halt-height=2000 gaiad start

This might get past the point on hub; but the fact it does is a huge red flag itself. Don't rely on this. The chain should be deterministic. It is broken.

[stakezone]

I have the same invalid port error as above when trying to create a channel.
