Hello Community / Tech Support… I have some GS1900-8 and a GS1900-10HP. I recently installed the firmware update V2.90(*.0) for both switches but the SNTP server fails to update the time stating that I'm having DNS issues. On checking SYSTEM→IP→DNS 1 is set to 0.0.0.0! I reverted to the previous firmware V2.80(*.1) all addresses are registered as expected. It may seem insignificant but all the logs will have the wrong time. I'll revert back to V2.80(*.1) for now until advised otherwise. Regards, A.
