Tried to upload a screenshot, but can’t for some reason. Error displayed in the webgui is

Error connecting to the marketplace server. Please check your settings in the System Console.

What are your System Console settings set to for Plugins?

Hi, @bediaa

As mentioned by @amy.blais earlier, the first step is to understand the current configuration of the Plugins page.

  • Can you provide the screen shot of the page either via System Console or from the config.json?

For config.json, this is the example command:

ahmaddanial@mattermost:~$ cat /opt/mattermost/config/config.json | grep -A19 "PluginSettings"
    "PluginSettings": {
        "Enable": true,
        "EnableUploads": true,
        "AllowInsecureDownloadUrl": false,
        "EnableHealthCheck": true,
        "Directory": "./plugins",
        "ClientDirectory": "./client/plugins",
        "Plugins": {},
        "PluginStates": {
            "com.mattermost.nps": {
                "Enable": true
            }
        },
        "EnableMarketplace": true,
        "EnableRemoteMarketplace": true,
        "AutomaticPrepackagedPlugins": true,
        "RequirePluginSignature": false,
        "MarketplaceUrl": "https://api.integrations.mattermost.com",
        "SignaturePublicKeyFiles": []
    },
  • What is the error that you are getting when you tried to click on the Plugin Marketplace from the list?

  • Can you also confirm the permission that you have set on the plugins and prepackaged_plugins are set to the mattermost user? For example:
root@mattermost:/home# ls -lAh /opt/mattermost/plugins/ /opt/mattermost/prepackaged_plugins/
/opt/mattermost/plugins/:
total 4.0K
drwxr--r-- 5 mattermost mattermost 4.0K May  5 00:43 com.mattermost.nps

I think these may answer your questions

$ grep -A19 "PluginSettings" config.json

        },

No plugins folder, but do have prepackaged. I execute mattermost under user ‘bediaa’

Error I get when navigating to the plugin marketplace

Just wanted to bump to see if anyone had any ideas? The error output doesn’t really give any hints on what the problem may be. All I get is a 500 error on command line debug as mentioned in original post.

Hi, @bediaa

Based on the statement here:

Does that mean that you were running on previous version prior to 5.22.1? If yes, what version was that?

I am trying to understand why the plugins directory is not available when you ran ls -lAh. Did you run it on root?

Since you are running mattermost under user bediaa, can you please provide the output of ls -lAh /opt/mattermost itself?

I want to make sure that the user bediaa has permission across all directories. If any of them are not under the bediaa, please run the following command:

sudo chown -R bediaa:bediaa /opt/mattermost/

Once done, please check if the error still persists.

Does that mean that you were running on previous version prior to 5.22.1? If yes, what version was that?

I don’t remember, but probably 5.20. I’ve kept it patched consistently since starting it in 2016. Almost every patch has been applied as they came out (sometimes missed a point release here and there).

I am trying to understand why the plugins directory is not available when you ran ls -lAh. Did you run it on root ?

The only user that has ever touched files in /home/bediaa/mattermost has been bediaa. All files are owned by bediaa. I ran sudo chown -R bediaa:bediaa /home/bediaa/mattermost and no change.

Bumping for visibility. Any ideas?

Hi, @bediaa

I am just trying to narrow down the potential root cause further. Is it possible for you to connect directly to Mattermost without the NGINX proxy and verify if the same issue persist?

If it connects successfully, let’s take a look at the NGINX configuration. There might be something that is misconfigured there based on Configuring NGINX as a proxy for Mattermost Server documentation.

Hmm, that’s a good idea. I did a SSH tunnel for 8065 to localhost and was able to login to the server completely unencrypted (bypassing nginx) using my local web browser (latest Firefox for Windows). Unfortunately, no change in behavior when trying to load the marketplace. Same error message in the webgui.
