c-lightning channel announcement/establishment issue
When the channel is opened the opening side of the channel chooses if the channel should be private or announced. Well actually the other side can also choose not to accept public channels. Maybe that has happened with both of your channels.
From the information you have we can only guess / speculate. 
 If you want to you can try to open a channel with my node (details at https://ln.rene-pickhardt.de - the node does not speak tor tough) but I could look in my logs if necessary and we could together debug what is going on.
