NGINX 502 error with MongoDB and Mongo Express

I created MongoDB and Mongo Express instances from the one click options. I thought it worked at first, but now I get the NGINX 502 error whenever I try to view a database.

Here is what I’ve done, checked or not done:

1. Confirmed both apps are running. I am able to bring up the ME screen and see the three default databases. However, when I click on “view”, I get the 502 error.
2. docker volume ls shows both persistent volumes.
3. The log for Mongo shows, if I understand it, authentication against the admin database:

{"t":{"$date":"2021-01-16T01:00:51.147+00:00"},"s":"I",  "c":"NETWORK",  "id":22943,   "ctx":"listener","msg":"Connection accepted","attr":{"remote":"10.0.1.11:54460","connectionId":22,"connectionCount":3}}
{"t":{"$date":"2021-01-16T01:00:51.253+00:00"},"s":"I",  "c":"ACCESS",   "id":20250,   "ctx":"conn22","msg":"Successful authentication","attr":{"mechanism":"SCRAM-SHA-1","principalName":"root","authenticationDatabase":"admin","client":"10.0.1.11:54460"}}

{"t":{"$date":"2021-01-16T01:00:51.262+00:00"},"s":"I",  "c":"NETWORK",  "id":22944,   "ctx":"conn20","msg":"Connection ended","attr":{"remote":"10.0.1.11:53852","connectionId":20,"connectionCount":1}}
{"t":{"$date":"2021-01-16T01:00:51.263+00:00"},"s":"I",  "c":"NETWORK",  "id":22944,   "ctx":"conn21","msg":"Connection ended","attr":{"remote":"10.0.1.11:53854","connectionId":21,"connectionCount":0}}

1. The ME log shows connection:

Waiting for srv-captain--mongodb:27017...
Welcome to mongo-express
------------------------

Mongo Express server listening at http://0.0.0.0:8081
Server is open to allow connections from anyone (0.0.0.0)
Database connected
Admin Database connected

1. Restarted the host VPS.
2. I haven’t changed any of the App Config settings for either service except to add (as a troubleshooting step) HTTPS for ME. However, I am not forcing it.
3. Read the docs on this issue
4. Searched both caprover and this repo for matching issues or additional suggestions.
5. ufw disable
6. Created a new database (successfully) but still get the error if I try to view it. And I’m confused by the namespace???

{"t":{"$date":"2021-01-16T01:31:05.925+00:00"},"s":"I",  "c":"STORAGE",  "id":20320,   "ctx":"conn35","msg":"createCollection","attr":{"namespace":"Test.delete_me","uuidDisposition":"generated","uuid":{"uuid":{"$uuid":"54452b55-f01d-400a-8121-a681d28cb589"}},"options":{}}}
{"t":{"$date":"2021-01-16T01:31:05.932+00:00"},"s":"I",  "c":"INDEX",    "id":20345,   "ctx":"conn35","msg":"Index build: done building","attr":{"buildUUID":null,"namespace":"Test.delete_me","index":"_id_","commitTimestamp":{"$timestamp":{"t":0,"i":0}}}}

I apologize if I’ve missed something, but I would appreciate some additional steps I can take.

Thank you.

Looks like it may have been fixed in mongo-express:0.54 image. Do this:

• Go to Apps > Mongo Express
• Go to Deployment tab
• From “Method 6: Deploy via ImageName” deploy this image: mongo-express:0.54

Perfect. That works. Thank you.

Good catch on the ME bug. I didn’t even think that might be it since I wasn’t having troubles my own recently set up ME (within the past few days).

Have a good night, and I do appreciate your quick response.
