Synapse 1.121.0 support could be done?

[GoddPerGugtern]

Hope see it ASAP

Is that why it fails to load data now?

For me the landing page is loading forever.

Testing synapse v1.129.0 and v1.135.0 - always showing the loading circle.

Just writing this comment bc the other issue about the infinite loading (justmentioned it) might have been a configuration issue…

Running synapse 1.136.0 - The github pages hostes instance works flawlessly. Self-hosted loads forever, even with reset configuration. No output in log.

May have found the issue in my configuration and fixed it. I could see the following logs in my proxy:

***.***.***.*** - - [03/Sep/2025:08:49:38 +0000] "GET /admin HTTP/2.0" 304 0 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:142.0) Gecko/20100101 Firefox/142.0" "-" ***.***.***.*** - - [03/Sep/2025:08:49:38 +0000] "GET /assets/index-wZ_5cIhW.js HTTP/2.0" 404 153 "https://domain.de/admin" "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:142.0) Gecko/20100101 Firefox/142.0" "-

Where the /assets section could not be loaded.

So I added the /assets location block to my synapse nginx reverse proxy config (see below, the last block was added). Below is the whole proxy setup to have the admin tool at https://domain.de/admin.

Pls note that I'm running the reverse proxy, synapse and the admin tool on the same server with docker; also restricted the endpoints with allow and deny rules, so you will have to adapt the IPs and maybe also the ports for your setup.

    # synapse-admin needs this path to be available
    location /_synapse/admin {
        # restrict access to admin net
        allow $ADMIN_IP_RANGE;
        # deny remaining
        deny all;

        # note: do not add a path (even a single /) after the port in `proxy_pass`,
        # otherwise nginx will canonicalise the URI and cause signature verification
        # errors.
        proxy_pass http://SERVER_IP:8008;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Host $host;

        # Nginx by default only allows file uploads up to 1M in size
        # Increase client_max_body_size to match max_upload_size defined in homeserver.yaml
        client_max_body_size 10M;
        client_body_buffer_size 10M;

        # Synapse responses may be chunked, which is an HTTP/1.1 feature.
        proxy_http_version 1.1;
  }

    # synapse admin web gui forwarding
    location /admin {
        # restrict access to admin net
        allow $ADMIN_IP_RANGE;
        # deny remaining
        deny all;

        # proxy the request
        proxy_pass http://$SERVER_IP:8080/;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Host $host;
  }
  
    # also forward static assets for synapse-admin
    # otherwise the admin gui will show the loading circle forever
    location /assets/ {
        # restrict access same as /admin
        allow $ADMIN_IP_RANGE;
        deny all;

        proxy_pass http://$SERVER_IP:8080/assets/;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Host $host;
    }

relevant: #688
maybe this also helps @hgue in #605

EDIT://

This was not really the fix as some more locations and assets needed to be loaded and couldn't because of the nginx config. So I changed the docker-compose.yml file for the admin tool to contain - BASE_PATH=/admin and rebuilt it. Also removed the /assets block again from nginx config.

change docker-compose.yml:

  synapse_admin:
    # https://github.com/Awesome-Technologies/synapse-admin
    container_name: synapse_admin
    restart: unless-stopped
    hostname: synapse_admin
    build:
      context: https://github.com/Awesome-Technologies/synapse-admin.git
      args:
        - BUILDKIT_CONTEXT_KEEP_GIT_DIR=1
      #  - NODE_OPTIONS="--max_old_space_size=1024"
        - BASE_PATH=/admin
    volumes:
      - /opt/synapse-admin/config.json:/app/config.json:ro
    ports:
      - "8080:80"
    networks:
      - matrix-network

rebuild only the admin tool with docker compose build synapse_admin && docker compose up -d synapse_admin
restart nginx docker restart synapse_proxy

I'm using Matrix Synapse 1.148.0 and while I can login, I only get this screen, not 100% if this is related to this issue:
