I have already running substrate-based node and I started to get error:

429 Too many requests: Too many connections.

This happens due to HTTP requests that my FE produces. After research I understand that I should configure --rpc-max-connections parameter, but I didn't find any info about how can I update this parameter on the already running network? Maybe I missed something? If yes, please let me know how can I do it)

Thanks a lot!

To the best of my knowledge, this can only be modified during startup.

At present, this flag does not support dynamic updates.

  • Thanks So, I should restart my node without cleaning state just add this parameter to startup script?! Feb 13 at 13:43
  • @ArtemLevchuk yes!
