Nginx (trilium in a subfolder): the rewritten URI has a zero length

[ElHado]

Hi,

first: Really a great program, thanks for sharing it and thanks for all the work and time you put into it!

I don't get trilium in a subfolder working right. Maybe someone can help me or give me a hint whats wrong. My https is managed before trilium.

I have no possibility to run it on a subdomain. The weired thing: I can open trilium with Chrome browser, but not with Firefox or Edge. I can also sync with the Windows Desktop client and I can send notes via webclipper from Chrome and Firefox. I'm not very good with nginx config files so I think I have a small thing wrong with it.

My trilium config:

[General]
instanceName=
noAuthentication=false
noBackup=false

[Network]
host=127.0.0.1
port=8080
https=false
certPath=
keyPath=

trustedReverseProxy=true

My nginx Block for trilium:

    location /trilium {
    	rewrite ^/trilium(.*)$ $1 break;
    	proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_pass http://127.0.0.1:8080; #change it to your IP and port
        proxy_read_timeout 90;
        proxy_redirect http://127.0.0.1:8080 https://xxx.xxx/trilium; #change them based on your IP, port and domain
    
    	error_log       /var/log/nginx/trilium.error.log;
    }

On Firefox and Edge I get the error 500 and in the error log it says: the rewritten URI has a zero length.

Thanks for your help in advance.

Sorry, posted a little too early. Seams like this slash at the end in the first line did the trick:

location /trilium/ {
    rewrite ^/trilium(.*)$ $1 break;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_pass http://127.0.0.1:8080; #change it to your IP and port
    proxy_read_timeout 90;
    proxy_redirect http://127.0.0.1:8080 https://xxx.xxx/trilium; #change them based on your IP, port and domain

	error_log       /var/log/nginx/trilium.error.log;
}

I thought I already tested it but it was maybe with other changes because I tried really much different things in this config.
