dropped incoming data from unknown supernode #31

Closed H-Maktub closed 6 months ago

H-Maktub commented 6 months ago

Hello, I use Supernode Federation, but only one edge is in a normal state. On other edges, only one supernode is online, prompting "15/May/2024 16:38:44 [src/edge_utils.c:2372] dropped incoming data from unknown supernode"

Whilst is it definitely unexpected to get an error for this config, you do have one strange setting: usually, all the supernodes are told about all their peers, so can you quickly try adding an appropriate supernode.peer= line to your supernode1 to point it at supernode2?

I'll probably need to dig deeper into the code to understand better what is happening, but will not get a chance for a couple of days. So, if that quick config suggestion gets things working better, great.

I have tried the method you mentioned, and there are still problems; but edgenode2 is normal. Is it possible to add an example of Federation configuration file?

I have added a quick example of the config needed with multiple supernodes in 27af40ca9942
