thanks.

Can you try installing with a version rather than main? Did you clone the release version or main? I'm actively developing things and haven't been able to do a prod test in a while.

If you can wait about a month I will have a major prod update.

[pwdel]

Read the directions here:

https://github.com/openpredictionmarkets/socialpredict/blob/main/README/STAGE_SETUP.md

That should help.

For your specific case:

When I go to jh-prediction-market.site it redirects me to https

Hence why when you do:

curl -I http://jh-prediction-market.site/
``1

It goes to permanent redirect.

> HTTP/1.1 308 Permanent Redirect

There are additional settings in Docker that you have to set in terms of the firewall...please see the STAGE_SETUP.md notes.

[pwdel]

This points to an edge-routing/TLS problem, not a DNS problem and probably not a frontend/backend app problem.

What your evidence says:

• DNS is good: jh-prediction-market.site resolves to 146.190.149.144.
• Port 80 reaches Traefik: HTTP/1.1 308 Permanent Redirect means Traefik is alive and redirecting HTTP to HTTPS.
• HTTPS reaches Traefik, but cert is wrong: self-signed certificate means Traefik is serving its default cert,
  not a Let’s Encrypt cert for jh-prediction-market.site.
• If the browser then shows plain 404 page not found, that is usually Traefik’s default 404, meaning Traefik did
  not match a router for that hostname. In other words, request is likely not reaching nginx/frontend.

Most likely issue: Traefik is running, but its Docker router for socialpredict-nginx-container is not being
created or not matching Host(jh-prediction-market.site).

Run these on the droplet:

docker inspect socialpredict-nginx-container
--format '{{range $k,$v := .Config.Labels}}{{println $k "=" $v}}{{end}}'

You want to see something exactly like:

traefik.enable = true
traefik.http.routers.social-predict.rule = Host(jh-prediction-market.site)

No http://, no quotes inside the host, no empty value.

Also check:

cat /home/socialpredict/.env | grep -E '^(DOMAIN|DOMAIN_URL|EMAIL)='
docker logs socialpredict-traefik-container --tail=100
cat /home/socialpredict/data/traefik/logs/error.log
docker network inspect socialpredict_external_network --format '{{range .Containers}}{{println .Name}}{{end}}'
curl -k -i https://jh-prediction-market.site | head -30

Expected network membership should include both:

socialpredict-traefik-container
socialpredict-nginx-container

One important security note: that admin password has now been pasted into a chat/log context. Treat it as
exposed and rotate it after the site is reachable.

hi @pwdel,

Thanks for your time and reply.

docker inspect socialpredict-nginx-container
--format '{{range $k,$v := .Config.Labels}}{{println $k "=" $v}}{{end}}'

You want to see something exactly like:

traefik.enable = true
traefik.http.routers.social-predict.rule = Host(jh-prediction-market.site)

No http://, no quotes inside the host, no empty value.

            **"traefik.enable": "true",
            "traefik.http.routers.social-predict.rule": "Host(`jh-prediction-market.site`)"**  is it correct? it has quotes ''

Also check:

cat /home/socialpredict/.env | grep -E '^(DOMAIN|DOMAIN_URL|EMAIL)='

root@marketplace-s-1vcpu-1gb-sfo3:~# cat /home/socialpredict/.env | grep -E '^(DOMAIN|DOMAIN_URL|EMAIL)='
DOMAIN='jh-prediction-market.site'
DOMAIN_URL='https://jh-prediction-market.site'
EMAIL='john@doe.com'
docker logs socialpredict-traefik-container --tail=100
empty

cat /home/socialpredict/data/traefik/logs/error.log
please see the attachment.

[pwdel]

Yes, this label is correct:

  "traefik.enable": "true",
  "traefik.http.routers.social-predict.rule": "Host(`jh-prediction-market.site`)"

The double quotes are just JSON output from docker inspect. The backticks inside Host(...) are expected Traefik rule syntax. Your .env values also look okay, and nginx + Traefik are on
the same external Docker network.

The important clue is this:

  curl -k -i https://jh-prediction-market.site
  HTTP/2 404
  404 page not found

That is Traefik’s own 404, not the app’s frontend 404. It means the HTTPS request is reaching Traefik, but Traefik is not routing it to socialpredict-nginx-container.

The next thing I would check is whether Traefik actually loaded the Docker provider/router. Ask them to run:

  docker exec socialpredict-traefik-container cat /etc/traefik/traefik.yml

Then:

  cat /home/socialpredict/data/traefik/logs/error.log

And specifically look for Docker provider errors like:

Cannot connect to the Docker daemon
provider docker error
network not found
field not found
router ... error

Also run:

  docker exec socialpredict-nginx-container nginx -T | head -80

If Traefik is routing correctly, then curl -k https://jh-prediction-market.site should hit nginx/frontend. Since it returns Traefik’s 404, the issue is almost certainly between Traefik
and its Docker-discovered router, not the app containers.

One likely hardening/fix to try in scripts/docker-compose-prod.yaml is adding explicit router/service labels instead of relying on Traefik defaults:

  labels:
    - "traefik.enable=true"
    - "traefik.docker.network=socialpredict_external_network"
    - "traefik.http.routers.social-predict.rule=Host(`${DOMAIN}`)"
    - "traefik.http.routers.social-predict.entrypoints=websecure"
    - "traefik.http.routers.social-predict.tls=true"
    - "traefik.http.routers.social-predict.tls.certresolver=letsencrypt"
    - "traefik.http.services.social-predict.loadbalancer.server.port=80"

That makes Traefik’s intended route to nginx unambiguous.

[pwdel]

@yxguyxgu did that work?

[yxguyxgu]

hi @pwdel ,

thanks for your help.

i updated scripts/docker-compose-prod.yaml and restart the services, ./SocialPredict down / up.

however, it still shows 404 error same as before.

please see the attachment.

if you have time, could login the vm and take a look.

thanks

i tried option2 local host, the http works, but the admin/password didnt work, so could not login.

create a new or keep the existing .env file, they had the same issues.

[pwdel]

Are you using a release or main? Please use the release version.

[pwdel]

At this point yeah I'm seeing your site but your site is on http so it will not be able to see the backend hence why you're getting the errors.

So if you visit here:

http://www.jh-prediction-market.site/api/v0/home

You a see a little json message saying, "data fro the backend," which shows that you have a backend that is up and available.

At this point there seems to be something wrong with your nginx settings. If you have Traefik working now, Nginx is not pointing to the correct thing(s).

[yxguyxgu]

Are you using a release or main? Please use the release version.

hi @pwdel ,

i installed release 2.1.0, but it had the same 404 issue.
