I'm following the instructions to install Nextcloud on an nginx server. I copy the configuration from the offical documentation, i set my server name and my ssl certificate path, and when i try to reach nextcloud from my browser i get

"500 Internal server error".

When i check in the error.log i get

rewrite or internal redirection cycle while processing "/index.php"

This is my configuration file:

I've searched for this problem, but haven't get solution yet. I have Nextcloud installed on https://example.com/nextcloud. Yesterday I installed Seafile, that works on https://example.com (I simply don't know, how to make it accessible from, for example, https://example.com/seafile) While I was setting it, Nextcloud was switched off by deleting link to corresponding file in sites-enabled directory. Seafile worked. But when I enabled Nextcloud, I got error 403 forbidden trying to access Seafile. I also enabled info level in Nginx and there I got next message:

I know I have asked this question before but i didn't get any answers for it.

How to install HAProxy and configure it in an Ubuntu server. I want to use it to map applications listening on various ports to specific URLs.

For example, if an app called page-designer is listening at http://IP:5000, then it should map it to http://IP/page-designer.

I have already installed the HAProxy package using sudo apt-get -y install haproxy. But what changes do I have to do in HAProxy main configuration file located at /etc/haproxy/haproxy.cfg before restarting the HAProxy service for the changes to take effect. And mainly after this how can I map my apps running on various ports to specific URLs like mentioned above?

haproxy.cfg

I'm looking for a recommended configuration for SSL/TLS in Traefik. I have set minVersion = "VersionTLS12" to avoid the weaker older versions and found the supported ciphers in Go. Cross-checking that with the recommendations from SSLLabs I came up with the following sequence (order matters):

I am using Let's Encrypt to install a free TLS/SSL certificate in my server. I followed the suggestion of Mozilla SSL Configuration Generator and configured nginx like this:

Hardware

• Raspberry Pi 2

Software

• Debian
  • YunoHost
    • Duniter

When I try accessing Duniter's web application page https://duniter-folatt.nohost.me/webui, I receive the typical nginx 502 Bad Gateway error.

I've also tried accessing the webui after starting duniter webstart with the same result.

I have an nginx 1.10.3 server running NextCloud and access it from various clients. The certificate is provided by Lets Encrypt and uses a 2048-bit RSA key.

All clients work fine, including web browsers, except those running on iOS 11 on an iPad or iPhone. The working browsers are Firefox 56 on MacOS and Linux, and Safari 11 on MacOS Sierra. The NextCloud client on Linux also works fine. On iOS, GoodReader has no problem accessing NextCloud as a webdav client. But Safari will not access it, claiming it could not access a secure connection to the server. The iOS NextCloud client returns an SSL error when it tries to connect (I presume it uses the same library as Safari to connect).

The error in the nginx log for when iOS (Safari or the NextCloud app) tries and fails to connect is:

I use Mozilla SSL Configuration Generator(https://mozilla.github.io/server-side-tls/ssl-config-generator/) to generate a configuration.

My selections are nginx and modern,the configuration has a piece of code like this:
