semaphore Problem: Some API endpoints stuck in "pending" state (e.g. /api/project/6/templates)

Issue

When accessing certain API endpoints, the request never completes and stays in a "pending" state indefinitely. Other API routes work normally.

The browser keeps waiting for a response (pending in Network tab) — the request just hangs.

*Additional Observations When the project has 8 or fewer templates, the API works fine.

Update

After further testing, I switched the database backend from PostgreSQL 16.10 to MySQL 8, and the issue completely disappeared.

Hi @Amzeratulz Did you use fresh installed Semaphore with Postgres?

I have the same issue — let me know if I can provide any details to help nail it down.

I run Semaphore via docker compose (semaphore:latest, postgres:17). I get this in the logs, no idea what it means:

@bartmichu is it full stack?

Nov 08 '25 19:11 fiftin

Hi @Amzeratulz Did you use fresh installed Semaphore with Postgres?

After further investigation, I found the root cause of the "pending" API issue: Initially, after switching to MySQL 8, the API worked fine. However, the issue reappeared.

The underlying problem is related to reusing the same Docker volume from previous installations. Old data in the volume can cause the API to hang.

✅ Resolution: Clearing the old Docker volume and starting with a fresh database resolves the problem, and the API endpoints respond normally.

Nov 10 '25 06:11 Amzeratulz

@fiftin It's not that simple, I'm afraid — the issue remains. Clearing Docker volumes doesn't solve the problem for me; I've already tried that. Here's what I do: I back up the Semaphore project, nuke the Docker containers, volumes, the whole setup, then start a new Compose project, restore the Semaphore settings, add repository keys, etc. Still stuck on the "Task templates" page.

Nov 10 '25 06:11 bartmichu

I should have mentioned that I’ve always used Postgres and never changed the database backend.

Nov 10 '25 16:11 bartmichu

@bartmichu Could you please provide full error stack.

Nov 10 '25 20:11 fiftin

@fiftin I run docker compose and this is what I get:

At this point, everything seems to be working fine — the scheduled tasks are running, and I can browse the UI — except for the Task Templates tab. When I navigate to Task Templates, Docker throws the following in the console:

I’m currently facing the same issue. I’m using Docker Compose with PostgreSQL 18 as the database. Everything appears to be working fine, except that the Task Templates page in the UI doesn’t load.

Same issue here with semaphore docker + SQLite. I cannot access all pages in the browser except /project/1/templates. My semaphore webUI is reversed-proxied by Caddy.

Docker Compose

services:
    semaphore:
        #ports:
        #    - 3000:3000
        image: semaphoreui/semaphore:latest
        environment:
            - TZ=${TZ}
            - SEMAPHORE_DB_DIALECT=sqlite
            - SEMAPHORE_ADMIN=${SEMAPHORE_ADMIN}
            - SEMAPHORE_ADMIN_PASSWORD=${S_SEMAPHORE_ADMIN_PASSWORD}
            - SEMAPHORE_ADMIN_NAME=${SEMAPHORE_ADMIN_NAME}
            - SEMAPHORE_ADMIN_EMAIL=${SEMAPHORE_ADMIN_EMAIL}
            - SEMAPHORE_ACCESS_KEY_ENCRYPTION=${S_SEMAPHORE_ACCESS_KEY_ENCRYPTION}
        volumes:
            - ${BASE_PATH}/semaphore/data:/var/lib/semaphore
            - ${BASE_PATH}/semaphore/config:/etc/semaphore
            - ${BASE_PATH}/semaphore/tmp:/tmp/semaphore
            - ${BASE_PATH}/semaphore/config/ansible.cfg:/etc/ansible/ansible.cfg # Override the default ansible.cfg used by Semaphore.
            - /mnt/user/Backups/komodo-servers-borg-repos:/backup-unraid # Path in which komodo server are backing up... See backup-docker-appdata.yaml
        networks:
            - semaphore-net
            - LAN-net
            
networks:
  semaphore-net:

I got the same problem

Nov 20 '25 19:11 Goldenflamer

Same, postgres 17.6, semaphore :latest tag, via podman, seems like app is out of sync w/ db migrations.

Nov 21 '25 01:11 flyingfishflash

Any workaround for this issue?

I recreated my whole setup as a solution.

@apedance, do you mean you replaced Semaphore with something else? If so, with what? Or, did you just wipe your entire Semaphore config and start fresh? Thanks!

a docker img with all in one. no split containers for db and webui. fresh start that is.

Updating to latest beta (v2.17.0-beta24) solved it for me on two instances.
