Experiencing same issue. Also problems with checking for updates.
Used to be okay until one of the updates to 42.2....wonder if it's related to the:
- Bug bsc#1027712 switch to new client side cipher suite default
* Updated default cipher suite from "DEFAULT" to "SUSE_DEFAULT"
* Updates previous patch curl-DEFAULT_CIPHER_SELECTION.patch
This change has caused problems with quite a few linux apps....
v12.5.6 of Workstation doesn't resolve issues either.
