My cardano node was 100% synced and it is running in production environment. But suddenly I am seeing that my cardano node block get backed and sync percent is 97.78%.

Error log:

    What you posted is unlikely to be the actual cause of the halt, because its messages that a normal running node also gets. What version of the node are you running? Nov 3, 2022 at 19:20

Recently, pre-production environment was re-spun (check "build-announcements" in IOG's Technical Community discord), I would suggest you to delete your db folder and use latest configuration from here.

  • I have downloaded latest cardano node and install it with latest config file. Now it is synced.
