Extrange :0 and no external acces

Hi, I runned Syncloud for tree years with no much problems…
But since the last 1 week or so, I can not get it from outside my network (my office).

If I look for t since Syncloud.org Devices, I see an extrnage “:0” at the end…

In Setting/acces, I see that “public port” is 0
If I try to change to 443, it shows this message:
"Unable to verify open ports, using device public IP: ‘xxx.xxx.39.52’ which is IPv4. Details: port is not reachable

The Upnp in my Router worked before… now seems that Syncloud can not “open” ports on Router

any idea?
