Version: 5.11.10

Firmware: 2.10.2 Build 202330704 Rel.64607

A month ago I installed an OC200 hardware controller at each of my two schools to monitor the EAP610's AP I have at each site. Cloud access was quick and very responsive until I upgraded the firmware on both OC200's to 2.10.2 Build 202330704 Rel.64607.

Now, the Cloud access is unusable. Webpages either load after several minutes or not at all. Often when a page get loaded there is an "This webpage was reloaded because a problem occured" message.

At first, I thought the problem was with my browser, internet connection or the Omada Cloud server itself. However, I went to one of my schools yesterday and connected to the OC200 directly using an eithernet cable. The behaviour was better, but each page still took up to a minute or longer to load. The slow response time made the interface frustrating to use.

I'm considering going back to the previous firmware version.

Thank you, Don.

I just fininsh adding another OC200 to a third location.

It's running:

Version 5.6.4

Firmware 2.6.1 Build 20220921 Rel.35903 

perfectly.

No issues.

I down loaded Chrome Version 115.0.5790.98 (Official Build) (arm64) to my MacMini and performace is back to normal.

Fails, for me, using Safari Version 16.5.2 (18615.2.9.11.10)

Resolved, see below.

Same or similar issue. I have an OC200, and I manage it via the cloud interface, https://omada.tplinkcloud.com. I last managed the network about 2 months ago and I cannot remember an issue. 2 days ago I updated the controller software and managing it via https://omada.tplinkcloud.com is unbearable slow now. Not sure if it's the version, or something else. It's not me as far as I can tell, everything else is fast and I am on an unrestricted 1GbpFibre internet link. OC200, 5.12.9. 1.26.3 Build 20230906 Rel.36269 The actual issue is clicking on anything on the web interface causes the browser page to freeze, then 8-15 seconds later it finally loads. Not other issues at all on the network. Frustrating.

Update: Yes, i was using Safari on a Mac Studio.... confirming that for me at least, it seems to be a Safari issue. I just opened it on Chrome and no issues at all.  Back to full speed.  Happy!

As of 5.12.9 it appears to be even worse. I now have the same issue on Chrome. No amount of cache flushing or 'private' browser sessions seem to make any difference. It's taking 1-2 minutes per click for the page to respond.

The common theme is IOS, more specifically iPadOS, as we do not have any hardware other than iPads at our site. For the record, standard IOS Omada app works just fine, but is crucially limited in what can be done with it. 
 

At this stage I'd be tempted to roll back to an earlier known working version but the irony is that without access to a Windows or similar desktop device it will be near impossible to do. 

  I just installed my system, everything was running fine until i upgraded the firmware of the controller, and now it's unusable on Safari on iPad.

There is an issue with the performance of the GUI when using Safari, this was mentioned in the release notes and they are working for a fix in a future update.

In the meantime its best using an alternative browser
