Hi @Swapnil_Musrif,
Is the Sonarqube hosted in IIS, if yes, then the issue could be with the IIS being unable to handle the query length.
Please take a look at this reply here - SonarQube project page does not show any projects - #7 by julienlancelot, as I was facing the same issue and this helped me resolve it.
And this is the article I referred to increase the max query length - IIS: Changing maxQueryString and maxUrl | My Tec Bits.
Thanks,
Aravind
