portainer-ce:2.32.0
Portainer authentication failed, status code: 403, error: {"message":"Access denied","details":"Access denied to resource"}

But errors don't occur every time; they do occur every once in a while

the 403 intermittent error usually means one of these:

1. session timeout - portainer sessions expire after some time. check your session timeout settings in settings > authentication.

2. if using edge agent, the token might be expiring. regenerate edge key and update your agents.

3. ldap/oauth sync issues - if using external auth, user permissions might be out of sync. try logging out and back in.

4. api rate limiting - if youre making many api calls, portainer might be rate limiting. check if error happens during high api usage.

5. check portainer logs for more details:

docker logs portainer 2>&1 | grep -i "403\|denied\|auth"

6. if using portainer behind reverse proxy, make sure headers are passed correctly:

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Real-IP $remote_addr;

7. browser cache/cookie issue - try clearing browser cookies for portainer or use incognito.

8. check if its happening for specific users or all users. if specific user, check their role permissions.

to debug further, enable debug logging:

docker run -d -p 9000:9000 \
  --name portainer \
  --restart=always \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v portainer_data:/data \
  portainer/portainer-ce:latest \
  --log-level DEBUG

this will give more info about why auth fails.
