Hi RayleighPopo,

I have the same issue with the same version like you 23.5.0-7-xxxx my alerts on telegram don’t tag markdown Y_Y

Rollback your version to stable version, easy.

  1. sudo su - librenms
  2. lnms config:set update_channel master
  3. cd /opt/librenms && git fetch --tags && git checkout $(git describe --tags $(git rev-list --tags --max-count=1))
  4. ./
  5. ./validate.php

and now your alerts work again
