If you get the following error after installing and calling up the url https://local.polydocs.io:12500/
, here are the reasons:
– DNS resolution of private IP addresses not possible.
– DNS resolution for domain names that refer to private IP addresses in the FRITZ!Box home network is not possible via the FRITZ!Box. This means that server services in the FRITZ!Box home network cannot be accessed via the domain name.
You may see one of the following error messages:
“DNS timed out”
“DNS request timed out”
*Caused*
For security reasons, the FRITZ!Box suppresses DNS responses that refer to IP addresses in your own home network. This is a security feature of the FRITZ!Box to protect against so-called DNS rebinding attacks.
If you use a FritzBox, you must first make the following settings in the FritzBox menu:
- In the FRITZ!Box user interface, click on `Heimnetz`.
- `Heimnetz` Click in the menu `Netzwerk`.
- Click on the tab `Netzwerkeinstellungen`.
In the Hostname exceptions `DNS-Rebind-Schutz section`, enter local.polydocs.io for which DNS rebind protection should not apply. Confirm with .
