@Mia-smith said in Need suggestion: Experiencing Persistent API Error: I also check this : https://community.nodebb.org/topic/17758/error-permission-for-opt-config-nodebb-in-installing-with-dockerlooker But I have not found any solution. Do you have any other problems with your Docker install? For example NodeBB can show all users IPs as localhost if server ports are blocked (communication between Docker app and host machine). It worked OK and stopped working?
