Sounds as if there is something wrong with the configuration when set to static IP.
Looks as if the Pi cannaot get access to the internet. Are the settings for DNS and gateway correct?
I think the easier/better way is to leave the Pi at Automatic IP and to set a DHCP reservation in your router. Then you do not have to worry about setting gateways etc. on the Pi, and the Pi can always reconnect to the router (even with a new IP).
Thanks for Your both replies.
Setting are lookin good.
However, meanwhile I did already what PaulM described.
That works fine and I’ll leave it that way.
