Hi It seems like I found a workaround: hard disable TLS 1.3 in OpenSSL:
/etc/ssl/openssl.conf: | [system_default_sect] | MinProtocol = TLSv1.2 | MaxProtocol = TLSv1.2 | CipherString = DEFAULT@SECLEVEL=2 Bastian -- Military secrets are the most fleeting of all. -- Spock, "The Enterprise Incident", stardate 5027.4
