Original GitHub issue: https://github.com/amnezia-vpn/amnezia-client/issues/1013

Describe the bug
Adding personal server, with non standard ssh port, disabled root login (meaning that I'm using different name for user).
This looks like, for example:

Server IP address [:port]
80.70.60.50:60606

SSH username
newuser

Password
correctpassword

The server adds correctly, but I can't install protocols, getting Error 300.
This happened after I tried to change amnezia to use new reconfigured port and username, after I changed them. I can connect with ssh with provided data just fine.

To Reproduce
Steps to reproduce the behavior:

Add new server
Enter ip address with non standard port
Enter non-root username
Enter correct password

Expected behavior
I expect to download the protocol and not get "incorrect data" error, as the server itself adds correctly.

Log files
I can attach them later.

Screenshots
Can't take screenshots of the mobile app

Smartphone (please complete the following information):

Device: Poco M6 Pro
OS: Android 14 + HyperOS 1.0.4.0
Version: 4.7.0.0

Server (please complete the following information):

OS: Ubuntu 20.04.6 LTS x86_64

After reading logs, I guessed that the file permissions are borked. For anyone with similar situation, found a solution.

/opt/amnezia/ contains Dockerfiles for building amnezia protocols. As previous files were owned by now disabled root, and that apparently Amnezia didn't use sudo in this case of getting dockerfiles, I've changed groups and permissions of all the folders in the aforementioned directories:

sudo chgrp -R $USER ./opt/amnezia/*
sudo chmod g+rwx -R ./opt/amnezia/*
cd /opt/amnezia/
ls -l

I had the same error and tried to resolve it changing directory /opt/AmneziaVpn rights.
But got the same ErrorCode: 300 SSH ....

I use newest protocol AmneziaWG (version 2.0). Most likely my version of AmneziaVpn application didn't supported this protocol.

To solve this issue install the newest version of AmneziaVPN application
