Hi Eva, after some other research about your issue and thanks to Richard Duivenvoorde that checked and confirmed the issue on his system using other tools, is now clear that the problem is not related to QGIS but: - to a misconfigured security connection protocol used by the WMS server at gibs.earthdata.nasa.gov (it uses an insecure SHA-1 hash function in some circumstances) - to a default higher security level connection (SHA-1 is not allowed) requested by the version of the openssl library (1.1.1f) shipped with Ubuntu 20.04 You can workaround the issue following the advice provided at https://askubuntu.com/a/1233456 Although it's not recommended to lower the security level of https connections, I've personally tested that solution and it works on my Ubuntu 20.04, allowing QGIS to connect via SSL with the WMS server at gibs.earthdata.nasa.gov. Hi Richard, you can also confirm the source of the issue checking that curl -v "https://gibs.earthdata.nasa.gov/wms/epsg4326/best/wms.cgi?SERVICE=WMS&REQUEST=GetCapabilities"; --cipher "DEFAULT@SECLEVEL=1" works. And also directly using openssl to connect to the server, checking that openssl s_client -connect gibs.earthdata.nasa.gov:443 do not works, while openssl s_client -connect gibs.earthdata.nasa.gov:443 -cipher DEFAULT@SECLEVEL=1 works.
