I am running NPM using docker-compse. where I ran
docker-compose pulland thendocker-compose up -dWhen the app started, I logged into the new version and instead of having the dashboard/proxy hosts I cannot see anything. I check the Chrome console tab and see a bunch of these:
Nginx Proxy Manager Version
2.9.4

Operating System
Alpine Linux 3.13.5, Docker 20.10.3, Docker-Compose 1.27.4

I also recreated the images to ensure it was built properly
docker-compose up --force-recreate --build -dThat did not fix the issue
Here is my docker-compose.yml
@danner26 commented on GitHub (Jul 4, 2021):
Just to ensure that the issue is not related to me being a smacker, I decided to fully shut down the containers, remove all images on the drive (that pertained to NPM), and do a full, fresh install (using the same data of course) and still no dice
Definitely a frontend issue in my opinion but I have no idea why if it is the latest stable release?
@Nozza-VS commented on GitHub (Jul 6, 2021):
I just upgraded from 2.9.0 to 2.9.4 and encountered this briefly, quick browser cache refresh did the trick
@danner26 commented on GitHub (Jul 6, 2021):
Thanks @Nozza-VS unfortunately that isn't the fix for me. I've tried incognito windows and other browsers without success. The same behavior is experienced
@Ceriwaen commented on GitHub (Jul 10, 2021):
I just experienced this as well. Downgrading to 2.8.1 and refreshing browser cache returned it to functionality.
@jc21 commented on GitHub (Jul 13, 2021):
This is not specific to 2.9.4. This issue pops up from time to time with some users. Forcibly clearing your browser cache has been known to fix this and the root cause of the problem is still unknown.
Personally I've never had this happen to me, I pull and run each release on my own production servers and don't encounter a caching problem.
It might be helpful if users would report their browser and version, in case this applies to something non-mainstream.
The UI's index HTML page includes the version as a get param for assets, ie:
src="/js/main.bundle.js?v=2.9.4"and this should be enough to cache bust, unless the caching mechanism is ignoring query params on urls (possible with some CDN's..). It could also be possible that the index HTML itself is cached, but then requests one of the JS files from the bundle that is not cached and causes a mismatch. But yeah this is all speculation until I can reproduce this.@TrustyTristan commented on GitHub (Jul 18, 2021):
I experienced this issue too.
Running Edge Version 91.0.864.70 (Official build) (64-bit)
Tried clearing site data via Developer console. No change.
Tested Incognito and there was no problem.
Cleared site data again and restarted Edge, still the same issue.
Going into Privacy, search and services > Clear browsing data > Cached images and files
This fixed it.
@Ceriwaen commented on GitHub (Jul 18, 2021):
Thanks @TrustyTristan! Going into Firefox settings "Cookies and Site Data" and selecting "Clear Data" with both "Cookies and Site Data" and "Cached Web Content" also resolved this issue for me.
@nalybuites commented on GitHub (Jul 23, 2021):
I'm also having this issue. Experienced with NPM v 2.9.4 and 2.9.5 in Chrome 91.0.4472.124. Clearing cached images and files did not resolve, but downgrading to 2.8.1 did.
@Goblin80 commented on GitHub (Jul 31, 2021):
Clearing cached images and files did trick.

Clearing cache on Firefox worked for me thanks.
@v3ss0n commented on GitHub (Sep 24, 2021):
