``` {EESSI 2025.06} [USER@LOGIN USER]$ git clone https://github.com/EESSI/test-suite EESSI-test-suite Cloning into 'EESSI-test-suite'... fatal: unable to access 'https://github.com/EESSI/test-suite/': Could not resolve host: github.com ``` The error is not cause by probles with the direct system resolver or NSS. I was able to trace the problem to c-ares. Overiding LD_PRELOAD, HTTP version, curl options or TLS did not do anything to resolve. So than an AI agent told me to take look at our `/etc/resolv.conf` file. Running `cat -A /etc/resolv.conf` showed that their were `^I^I` empty tabs in the file. Our admins than confirmed that removing these tabs resolved the issue. They also indicated that `libresolv.so` might not be picked up correctly in the compat layer. Which might it cause the failure of parsing `/etc/resolv.conf`
