Help with mempool please

[VegArchie]

I am trying to get mempool (docker implementation) to connect with Fulcrum. I am getting the following repeating errors:

Is there a config setting (for either mempool or fulcrum) I could have missed (I have tried several)? FYI, Sparrow wallet connects on 50001 properly.

I tried the absolute IP address and I get different errors based on someones recommendation that it was a network/docker issue.

Anyone know what these errors indicate? What parameters are invalid?

I tried without using docker and get a similar problem:

Jun 4 12:28:13 [134278] DEBUG: Electrum attempting reconnect... Jun 4 12:28:13 [134278] ERR: Electrum error: {"errno":-111,"code":"ECONNREFUSED","syscall":"connect","address":"127.0.0.1","port":50002} Jun 4 12:28:13 [134278] ERR: Electrum error: {"errno":-111,"code":"ECONNREFUSED","syscall":"connect","address":"127.0.0.1","port":50002} Jun 4 12:28:13 [134278] INFO: Disconnected from Electrum Server at 127.0.0.1:50002

eventually got it working through brute force trial and error. Had to use absolute IP address of the machine

Ah I was going to say this is just some network setup issue outside of Fulcrum. Glad you figured it out!
