I've been running several instances nginx proxy manager for a while and using a python script I wrote to keep them synchronised but lately I've been having them crash more often than usual.
I'm tossing up between rebuilding it to aim for better stability or looking at an alternative, so figured I'd ask the community for alternatives
Ideally I would like the ability to have 2 or more instances synchronised but not really important as long as they can share the same certificates
Doesn't need any other fancy features as it's mostly for my internal services with just a few opened for outside access
*Edit
Seems swag might be worth a look, thanks all
Just out of curiousity:
Why are you running multiple instances? I assume because of HA/failover. But do you really need that? I know that most setups already have a single point of failure elsewhere. IMHO you are better off by making the reverse proxy or host of the reverse proxy more stable. I even multiple point of failures, such as my internet connection and modem.
An alternative would be to front your Nginx Proxy Manager with another proxy, such as HAProxy or Traefik. Both are designed for HA deployment and can also do health checks to decide what traffic to redirect to what endpoint. An HAProxy example and a Traefik example.
