I just realized that certain links of my website lead to "502 Bad Gateway" error. For example, https://v2a.10studio.tech/10studio/auth/google, https://v2a.10studio.tech/auth/google, https://v2a.10studio.tech/10studio/auth/microsoft, https://v2a.10studio.tech/auth/microsoft. I'm pretty sure that those links worked several weeks ago, I don't know what happened.
The website https://v2a.10studio.tech/ is still working. https://v2a.10studio.tech/#/sign?next=/ contains the buttons clicking on which lead to the broken links.
Here is docker-compose.yml

}
Could anyone help?
PS: I changed some setting (especially SSL certificates) for funfun.io in CloudFlare several weeks ago, i don’t if it is related. I don't know if this Proxy status
(DNS only
or Proxied
) has an impact.
Edit 1: here are some docker logs:
