FAQ and Troubleshooting

  1. FedCloud client gives error message "SSL exception connecting to https:// ..." when connecting to some sites

Some sites use certificates issued by national certificate authorities that are not included in the default OS distribution. If you receive error message "SSL exception connecting to https:// ...", follow instructions for installing EGI Core Trust Anchor certificates and add them to the certificate bundle of Python requests. For quick test in virtual environment, just execute the following commands. See this README.md for more details.

$ wget https://raw.githubusercontent.com/tdviet/python-requests-bundle-certs/main/scripts/install_certs.sh
$ bash install_certs.sh

  1. FedCloud client frozen during initialization (mainly on virtual machines at some sites)

It is a known problem of libsodium which is used by oidc-agent Python library. The problem is described here. Check the entropy on the VMs by executing command "cat /proc/sys/kernel/random/entropy_avail", and if the result is lower than 300, install haveged or rng-tools. On VMs with Centos, you also have to start the daemon manually after installation (or reboot the VMs)
