After changing a groov EPIC hostname, browser access by name can fail even while access by IP address continues to work. This symptom points to hostname resolution or name-to-IP association, not loss of basic IP connectivity. Clearing the browser cache alone does not correct a stale or missing network name record.
Identify the Failure Boundary
Open groov EPIC by its IP address and inspect the configured hostname in groov Manage. Confirm that the applied name matches the intended spelling. If IP access works but hostname access does not, keep device connectivity and hostname resolution as separate diagnostic paths.
| Observation | Supported conclusion | Next check |
|---|---|---|
| IP address opens the device | Basic IP connectivity is available | Inspect hostname resolution |
| Hostname does not open the device | The name is not resolving to the reachable IP | Check the router's name-to-IP association |
| Browser cache was cleared without improvement | Browser caching is not the confirmed cause | Continue with network-side checks |
Validate the Hostname
Use a Linux-compatible hostname with no spaces or special characters. If the configured name already meets those constraints, do not assume the name itself is defective; proceed to the network registration path.
The factory hostname pattern is opto-xx-xx-xx. Determine whether the router previously displayed that factory name and whether it now displays the replacement name.
Check the Router Association
The leading hypothesis is that the router retained the old hostname-to-IP relationship or did not accept the new hostname. The evidence does not establish whether groov EPIC uses a static or dynamic IP in this case, so identify that setting before interpreting the router's device list.
- Access groov EPIC by IP address and confirm the hostname shown in groov Manage.
- Determine whether its IP configuration is static or dynamic.
- Inspect the router for the EPIC's current IP address and associated hostname.
- Compare the router entry with the hostname shown in groov Manage. If they differ, involve the network administrator because the corrective action depends on the router and network configuration.
Verify the Result
Verify that the router associates the new hostname with the same IP address that successfully opens groov EPIC. Then retry browser access using the new hostname. Success requires both paths to reach the same device; until name resolution is corrected, continue using the IP address as the confirmed access method.
FAQ
Why can I reach groov EPIC by IP but not hostname?
The network can reach the device, but the new hostname is not resolving to that IP address. Check the hostname shown in groov Manage against the router's hostname-to-IP association.
What hostname format should I use for groov EPIC?
Use a Linux-compatible hostname without spaces or special characters. Confirm the applied spelling directly in groov Manage.
Why did clearing the browser cache not fix groov EPIC hostname access?
The failure may reside in the router's retained or missing hostname-to-IP relationship rather than the browser cache. Verify whether the router replaced the factory opto-xx-xx-xx name with the new hostname.
