### My YunoHost server
**Hardware:** Raspberry Pi at home
**YunoHost version:** 4.2.6
**I have access to my server :** Through SSH
**Are you in a special context or did you perform some particular tweaking on your YunoHost instance ?** : / yes
**If yes, please explain:**
changed .noho.st domain and moved converse app to im.personal.domain.tdl
### Description of my issue
xmpp and converse app both worked fine (almost, because I had problem with xmpp-upload with my own domain, but worked fine with .noho.st domain) but I changed .noho.st domain recently and moved converse app to a personal subdomain.
I think this converse app moved is NOT the problem because using external clients (conversations android app) I can’t not log in either.
So I guess some nginx & metronome & dnsmasq missconfiguration is happening.
I did not manually change any file, but in browser console (F12) it fails to connect because of CORS policy (cross origin resource)
I have `--force` yunohost tools regen-conf for nginx and dnsmasq and metronome, and have reviewed logs but I’m not savvy enough to see there any valuable info ☹
I have another app/services (nextcloud, wiki, …) all working fine (AFAIK).
Browser console message is similar to this (example):
just changing my domains on ynh
I’ve read I need to manually allow this on my server, but I guess if this was working fine until recent changes then it should also work if I force configuration reset on those services… unless I reconfiguring (forced) the wrong services.
Please would anyone suggest any hint and try to solve it? I can’t use xmpp with my server right now with any client and or account I’ve tried.
edit: I’ve a valid letsencrypt certificate for all involved domains (as seen in webadmin and browser)
edit2:
`ynh.domain.tld` is my main domain (sso portal), **users** (user1@ynh.domain.tld) can log in xmpp server.
users using “user1@my\_ynh.noho.st” (user1@im.domain.tld either) can’t log in.
`im.domain.tld` is where _conversejs_ app is installed
Few days ago, before moving conversejs do new domain, I could log in with any of the users, and because [user1@myynh.noho.st](mailto:user1@myynh.noho.st) could use xmpp-upload withou issues then there was no problem, but now I can not use this login.
If I were able to solve xmpp-upload issue with ynh.domain.tld this would be a minor problem for my relatives ☹
Thank you

Hi, please could anyone point me about the possible root cause of my problems? **THANK YOU.**
I would appreciate any **hint** in the direction I should search, I know you may not can provide personalized support 😅 to everyother dude around here
I guess is a particular problem to my instalation, because there’s no much info about issues with xmpp-upload in this forum (besides let’s encrypt renewals). Could be this a certificate issue?

Doing `dig` on _xmpp-upload_ subdomain I **got the same info than** muc, pubsub etc. and text messaging works fine. So I **guess** xmpp-upload DNS is well configured.
I have not chage metronome and converse default settings (actually I forced configuration to defaults **after** some tests), and restart.

`ls -la` on /var/xmpp-upload/ynh.domain.tld/
`drwxr-sr-x 10 metronome www-data 4096 Jul 11 08:14 upload`
inside `upload` **there are some few folders** (named with some key-id like above described) with NO content at all. I guess they were created from failed uploads.

It’d be nice to add pictures and sound records support for my family. Thank you **any way** 😉

I had similar problem with metronome service shutting down when I try to log in.
Searched for solutions without luck.
So I moved to nextcloud talk

thank you **jarod5001**
I will take in to consideration your “solution” if I can’t solve upload problem.
I’m also considering **dendrite\_ynh** even it is NOT fully implemented yet.
