The hostnames of the server addresses that the inverter needs for a successful Internet connection cannot be resolved to IP addresses. This may be related to an incorrect DNS setting.
Proceed as follows:
- If a static IP address is used, make sure on the user interface of the inverter under "Communication" - "Network" that the stored DNS address matches that of the router.
- If resolution is still not possible, an external DNS can also be used instead of the DNS address of the router. To do this, set the DNS address in the network settings of the inverter to 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare), for example.
- If resolution is still not possible, please check the DNS settings of the router.
