A proxy may be set by editing the user_conf file.

Navigate to user_conf:

• Windows: C:\ProgramFiles\OxfordNanopore\MinKNOW\conf\user_conf
• Mac: /Applications/MinKNOW.app/Contents/Resources/conf/user_conf
• Ubuntu: /opt/ont/minknow/conf/user_conf

Edit this portion:

"proxy": {
"cereal_class_version": 0,
"use_system_settings": true,
"auto_detect": true,
"auto_config_script": "",
"https_proxy": "",
"proxy_bypass": ""

https_proxy should be in one of two following formats:

• scheme://[username:password@]host:port
• "http://domain\\username:password@host:port"

Where "scheme" is one of https, socks, socks4 or socks5.

Please be aware that if you are using the format user@password in the proxy URL then make sure to scrub it from /etc/apt/apt.conf , /opt/ont/minknow/conf/user_conf , and bashrc (e.g. /etc/environment or ~/.bashrc) before collecting the logs and sending them to us.

If you do use the password, and if the password contains special characters, it needs to be percent-escaped in the URL, e.g. !@#$%^ should become %21%40%23%24%25%5E .
