I spoke to our security team. I was advised to use corporate root.crt. I
changed it in the project, but a new error appeared:
I0228 20:50:39.519296300 14294 http_connect_handshaker.cc:329] Connecting

I tried changing the environment variable
TSI_OPENSSL_ALPN_SUPPORT=0
But the error repeats itself :-(
