Loading balance 525


it was working fine till few days ago…
my server 1 and server 2 got ssl, both working fine when accessing https://server1.domain.com and htpps://server2.domain.com but from loading balance app.domain.com it is giving me an error 525, no idea what else I can do, I didn’t change anything it just stop working

I paused Cloudflare and all my domain and subdomains working fine with https (lets encrypt)
when I turn off all Cloudflare proxied the loading balance subdomain cant find any SSL certificate

And I keep getting: API Request Failed: POST /api/v4/accounts/{redacted}/intel/attack-surface-report/checkers/spf_check (503) when I am logged in Cloudflare dashboard


Are you using Cloudflare Load Balancing feature or rather doing “load balancing” on your origin host/server via HAProxy or Nginx or some other? :thinking:

May I ask what SSL option have you got selected under the SSL/TLS tab at Cloudflare dashboard for your domain ( Flexible, Full, Full Strict … )?

There are topics about this and this is an ongoing warning on the dashboard which is going to be resolved soon I believe:

Hi, I am using Full Strict and Cloudflare loading balance, about the API problem I tried that link and nothing but that is not even that important, getting loading balance working is the most important
