Are you saying you know with certainty the test should pass in your environment? Can you confirm things that require

Yes. Activity and logging show current logs entries.

@rchaconmolero this would be interesting because what that test does is testing to access your instance and check the returned mime type. Meaning if your server can not resolve its own host name it will fail here.
Also it would be really helpful if you could set the logging level to debug and send the logfile or at least search the log for an entry like the following and send that entry if it exists:

Specifically*: At least one of Nextcloud's configured *Or at least that's my take from my first read though of this recently added code |

In Chrome or webserver, URL --> "https://next01d.canal-sur.interno/apps/settings/js/esm-test.mjs" /**

@susnux should we add a
to the httpClient params? |
Yes! I wonder why it did work when I tested it. This will probably resolve this issue! |

In my case, with 'allow_local_address' => true, in config.php does not resolve the problem. |
|
Same here. The output of curl shows it being returned as content-type: text/javascript , however I still get the error show. Adding allow_local_address to the config.php does not change anything. |

Hi @jameskimmel:
If you're truly using Nginx in front of Apache, then it sounds like your real issue is that your Apache environment isn't set up to use the distributed Please shift this discussion for deeper troubleshooting to the Help Forum - https://help.nextcloud.com - so that developer inboxes aren't getting filled up with each comment here. :-) |
I do not use self-signed certs. My certs are not expired.
My server can connect to itself.
I use apache2.

Just for the ones deploying nextcloud on docker with nginx proxy, just deployed this version of nginx.conf (mine was quite outdated): https://github.com/nextcloud/docker/blob/master/.examples/docker-compose/with-nginx-proxy/mariadb/fpm/web/nginx.conf And error just went away:
Curl without mjs support: Curl with mjs support on nginx: On my test server Nextcloud general settings doesn't show the issue anymore as you can see on the previous image, on my production server it shows it but when i curl esm-test.mjs it responds correctly:
So i suppose that on PRO all is working fine anyways. |
|
Always remember: Your webserver needs to be able to connect to one of the If it still happens even if you check the points from above, please open a NEW ticket including LOG ENTRIES for the setupcheck with DEBUG logging enabled. |
|
I was able to fix the error message; there was still a wrong host entry in /etc/hosts. With "PUBLICIP your.nextcloud.com" the error message has now disappeared. Just a little tip, maybe check the host file :) |
Yes, if you use Unix with Docker and revers proxy is install in another VM. Easy way diagnostic this problem is call "curl -I https://our.nextcloud.com/apps/settings/js/esm-test.mjs" with external VM if you get content-type: text/javascript, you have problem with hosts file. |
|
The test for .mjs file fails also on a site protected with ssl client certificate, as it cannot use any. |
|
I have this issue in my Nextcloud due to my setup using Docker containers and reverse proxy, the main URL for the Nextcloud instance is not accessible by the Docker container itself. This is because Note that this does not have HTTPS though. I tried to add this as a trusted domain in the config in the hope that it might try to use it in the Javascript check but it doesnt: Is there anything else I can do? |
|
You could set |
Thanks, the first option does work, but won't this be overwritten whenever the Docker image is updated? Not a sustainable fix I think. I already have overwrite cli url set to the public URL of the Nextcloud so I can't change this. |
|
OK - seems I can add host-specific DNS override for the container with the argument I think this is sufficient to fix the issue |
Hello everyone.
In docker it would be something like Best |
Hi, have you checked that this fix persists after a reboot? As I believe by default, Docker issues IP addresses in the Docker network randomly, so there is no guarantee your caddy container will get the same Dockernet IP every time. |
|
It does persist a reboot. |
|
Just quickly confirming this on my end. I hope to find time to pin this down and report back in the coming days. |
Not sure what there is to confirm? This occurs when Nextcloud cannot reach itself by the URL you have configured for it. Considering this is most likely the case in setups where people are using reverse proxies, which you are doing, it's almost certainly the cause of your issue. |
|
I've noticed browser:
I'm not doing reverse proxy but wonder if there's a difference between curl and the browser..? |
Hi, While you may have found the cause of why this issue occurs in your circumstances, that does not mean it is the source of the issue and the only reason it's triggered. As in the O.P's issue; this occured upon an update of Nextcloud - where the issue was not present previously. Also being that mine is deployed from turnkey it was/is configured correctly to reach the URL and prior to the update had no issue so let's refrain from jumping to conclusions as to the cause. Regards |
|
On my instance, the fix was to disable CloudFlare proxy. The proxy was transforming text/javascript to text/html. There's potentially a "worker" solution for this in CloudFlare, but I did not pursue it. It is also noteworthy to pay attention to apache Some instances of Apache use |
Possible solution for nginx.I am running nextcloud on nginx and updating this part of the nginx nextcloud server config fixed this issue.: I hope it helps someone ! |
|
Just in case anyone wants a fix for this error on openLiteSpeed server. Go to this folder /usr/local/lsws/conf Restart server and off you go

Thanks ondrejlohnisky You're contribution here finally led me to a solution. I had to remove $asset_immutable but doing so finally resolved the issue for me. location ~ .(?:css|js|mjs|svg|gif|png|jpg|ico|wasm|tflite|map)$ { |
|
@jlhollowell & @ondrejlohnisky: If adjusting I've seen some tutorials floating around where people appear to attempt to correct what they thing is a typo in the earlier $asset_immutable definition. But doing that is what breaks the later reference to it. The correct config (full can be pulled from the link just mentioned) is below: [...] |
