What version of SonarQube are you using?
Did you set Server base URL in Administration->General settings -> General?
Can you ping that hostname through CMD? Do you get any response?
Is it self compiled version of SQ? Please be specific on that part, there are differences between 8.X versions. We had an issue on IE, which has been resolved recently, so maybe try different browser depending on the version you are using.
I’m using Sonarqube community version- 8.4.1.35646. Also I am using IE. I’ll test using chrome after installing chrome browser on server. Would you like me to verify any further details?
