Hello, I seem to have run into an issue with my configuration. I am running Fedora 41, basic lamp stack, I configured my apache to reverse proxy over to coolwsd (installed via package) according to the install guide (copy/paste). The error returned when attempting to open a document is (tokens ommitted) Dec 31 11:08:33 Alfred coolwsd[716600]: wsd-716600-716613 2024-12-31 11:08:33.094068 -0500 [websrv\_poll] ERR #23: Unknown resource: /cool/(preconfigured domain for nextcloud)%2Findex.php%2Fapps%2Frichdocuments%2Fwopi%2Ffiles%2F(file token)?access\_token=(access token)&access\_token\_ttl=0/ws GWebSocket, host: collab, path: 4 This results in a failure to open the document, as expected with this error. ---

Hii @FamousL It seems like you’re encountering an issue with your reverse proxy setup, particularly with how URLs are being forwarded to `coolwsd`. This type of error often arises due to improper handling of URL encoding in the reverse proxy configuration. Check below points to resolve the issue 1. **Improper URL Encoding in Apache Configuration** Apache might be misinterpreting or altering the encoded URL when forwarding it to `coolwsd`. Ensure you have the following directive in your Apache configuration for the reverse proxy: 2. **Check the `coolwsd.xml` Configuration** Make sure your `coolwsd.xml` file is configured to accept the domain for your Nextcloud instance. For example: 3. **Verify the Apache Proxy Modules** Ensure that the necessary modules are enabled for Apache: 4. **Test Direct Access to `coolwsd`** Test if `coolwsd` is accessible directly by visiting `http://127.0.0.1:9980/hosting/discovery`. If this returns a valid XML response, the `coolwsd` service is running fine, and the issue is isolated to the reverse proxy. 5. **Check Logs for More Details** Review both Apache and `coolwsd` logs for additional insights. For example: 6. **Update Apache Configuration for Path** If the error persists, ensure that the `ProxyPass` configuration explicitly includes the `/cool` prefix: Please check above points and let me know, we will go through the issue together if not solved. Thanks, Darshan ---

Hello, going through point by point 1. i have /cool going to [http://127.0.0.1:9980/cool](http://127.0.0.1:9980/cool) is that incorrect? I tried both and am getting the same error either way 2. I have my nextcloud server set in the wopi storage section, specifically the alias\_groups 3. httpd -M |grep -E “proxy|headers” headers\_module (shared) proxy\_module (shared) proxy\_ajp\_module (shared) proxy\_balancer\_module (shared) proxy\_connect\_module (shared) proxy\_express\_module (shared) proxy\_fcgi\_module (shared) proxy\_fdpass\_module (shared) proxy\_ftp\_module (shared) proxy\_http\_module (shared) proxy\_hcheck\_module (shared) proxy\_scgi\_module (shared) proxy\_uwsgi\_module (shared) proxy\_wstunnel\_module (shared) proxy\_html\_module (shared) proxy\_http2\_module (shared) 4. This part does return valid xml, and does so through the reverse proxy as well. 5. apache isn’t reporting any errors, and coolwsd’s log file is not even showing up. ---

1. **Reverse Proxy Path** Update your Apache configuration to forward `/cool` directly to `http://127.0.0.1:9980/`: 2. **Verify WOPI Configuration** Ensure `` in `coolwsd.xml` has the exact Nextcloud URL: Check both `coolwsd` and Apache logs for errors: - Apache logs: `/var/log/httpd/error_log` or `/var/log/apache2/error.log` - `coolwsd` logs: `/var/log/coolwsd.log` ---

1. done, however the site you linked has it configured differently, perhaps it needs updating? ProxyPass /cool [http://127.0.0.1:9980/cool](http://127.0.0.1:9980/cool) ProxyPassReverse /cool [http://127.0.0.1:9980/cool](http://127.0.0.1:9980/cool) 2) I made the change 3) no errors, coolwsd doesn’t seem to have a log Same error as before shows up in journalctl ---

Issue seems to be with token. 🤔 ---

**Error in `journalctl`** The error suggests `coolwsd` is unable to process the WOPI URL. Common causes include: - **URL Encoding Mismatch:** Ensure `AllowEncodedSlashes NoDecode` is set in Apache. - **Token Validation Failure:** Verify the WOPI token in the URL is correct. Check the Nextcloud logs for WOPI errors: `/var/log/nextcloud.log`. Can you **Share Details** : - The full URL from the `journalctl` error (omit tokens). - Relevant sections of `coolwsd.xml` and Apache config. ---

**Unknown Resource Error (`ERR #33`)**: - This typically indicates a mismatch in the routing or configuration between Collabora Online and Nextcloud. Specifically, the WOPI request is not being properly recognized or routed by the Collabora Online server (`coolwsd`). #### Proxy Configuration Adjustments Ensure your Apache or Nginx configuration is handling encoded slashes properly. For Apache: For Apache ```auto AllowEncodedSlashes NoDecode ProxyPreserveHost On # Adjust ProxyPassMatch ProxyPassMatch "^/cool/(.*)/ws$" ws://127.0.0.1:9980/cool/$1/ws ``` For Nginx: ```auto proxy_set_header Host $host; proxy_set_header X-Forwarded-Proto $scheme; proxy_pass http://127.0.0.1:9980; ``` #### Update Nextcloud and `richdocuments` App - Ensure you are using the latest version of Nextcloud and the `richdocuments` app. Note: check the Nextcloud forums at [https://help.nextcloud.com/](https://help.nextcloud.com/) to see if there are similar issues or insights shared by other users. This might help pinpoint a solution or provide additional ideas. ---

The slash encoding was already present (just above the quoted section, i apparently mangled the markup) Adjusted proxypass, error appears the same, however it is now 38 and not 33. richdocuments is the latest version ---

@FamousL Have you investigate on Nextcloud forum about this issue ? I would suggest to first check on NC forum/ community section [https://help.nextcloud.com/](https://help.nextcloud.com/) @FamousL as go through all the possible solution and it might seems to be and issue with communication issue between NC and COOL. I also encourage you if you can add a detailed note and file a GitHub issue ticket on this ? > **[Build software better, together](https://github.com/CollaboraOnline/online/issues/new/choose)** > > GitHub is where people build software. More than 100 million people use GitHub to discover, fork, and contribute to over 420 million projects. Thank you for your amazing effort to describe the problem. Now a little help on filing the problem will also help to investigate and fix this problem Thanks, Darshan ---

lol glad to see it wasn’t just me missing something obvious, I had searched the nextcloud forums, and just a general “all over the place” type search but it hadn’t turned up anything addressing my specific problems. I can open a ticket, didn’t want to open one and find I misplaced a character in my configuration. Thank you very much, I appreciate the debugging help. ---
