docker droplet with nginx proxy manager and various other dockers

Hi All,

New to digitalocean but experienced enough with nginx proxy manager (NPM) and dockers. I have set up NPM and 2 other dockers. Everything is reachable by IP number of the droplet and port number and if I ping the (sub) domain I get the result I expect with the ip numbr of the droplet. However I am not able to use NPM as I am used to IE ip of droplet:port for a proxy host. I also tried localhost:port and 127.0.0.1:port. Mainly the result is # 504 Gateway Time-out openresty I also got some json responses with using localhost:port:

**{**"status": "OK","version": **{**"major": **2**,"minor": **10**,"revision": **4****}****}**

But I have no clue where that comes from. I have searched high and low but could not find any information that helped me address the issue. The dockers themselves have no issue, I get all the expected results when using droplet0ip:port. IE a webpage displays and I can also send a push message that way. Any tips would be appreciated.

Kind Regards,

Gerrit Kuilder
