Hi,  
I just reverted to Core 29.3.1 from Knots and noticed a warning icon appears on the Datum Gateway service.

When I click on “Auto Config” on the Bitcoin Core dependencies, I saw the following and accepted/saved the modification but the warning still appears on the Datum Gateway service.

Note: All services appear to be running fine nonetheless and my solo miner looks fine as well.

I believe you’ll need to use the latest versions of these services available on StartOS v040.

I am having an issue with Datum and Core.

See:

> [@Problem with Datum and Bitaxe resets peer and StartOS v 0.4.0.1](https://community.start9.com/t/problem-with-datum-and-bitaxe-resets-peer-and-startos-v-0-4-0-1/5534):

> Error on Bitaxe logs: 192.168.x.y:23334 (errno 104: Connection reset by peer). I don’t see any login attempts or errors in the Datum logs. Datum v. 0.4.1:15 Any ideas? \*\*\*UPDATE I’ve check port access to :23334 ie. nc: connect to 192.168.x.y port 23334 (tcp) failed: Connection refused I tried to rebuild the service but the issue persists.
