Updating port forwarding for your router failed
Note: This guide gives examples using the WD My Cloud NAS.
Other NASes will differ slightly, but will be similar.
If you do NOT receive the above messages on BOTH ports, then there are a few possibilities (in no particular order)1) Your ISP or router are blocking the connection. may be undesirable but still should work It's not "slow" or "sometimes servers are down".
Now I tried the manual port forwarding setup as you mentioned and it still did not work because it could not connect.
I reverted back to "Automatic" and now it connected with a "relay connection" and not direct connection any more.
In the Pop-up that appears, click the "Manual" button, and note the two ports listed.
By default, the Cloud will have ports 80 and 443 already entered in the blanks.
