I use the axon server as a remote server in spring boot. not in the localhost. but when the spring boot application connects to the server it fails and show the following error.

Connecting to AxonServer node [192.168.99.100:8124] failed: INTERNAL: Panic! This is a bug!
Failed to get connection to AxonServer. Scheduling a reconnect in 2000ms
[Channel<29>: (192.168.99.100:8124)] Uncaught exception in the SynchronizationContext. Panic!

  • Please clarify your specific problem or provide additional details to highlight exactly what you need. As it's currently written, it's hard to tell exactly what you're asking. – Community Sep 03 '21 at 14:54

it looks like your Spring Boot app misses some dependencies. Perhaps you could include the Axon Framework BOM or use the Axon Initializr? That should make sure you have everything configured as needed.
