Safari & GUI Caching Issue

Hi Folks,

Brand new to this community and TrueNAS so I apologize if this is a repeat question. I couldn’t find the answer in the forum myself - but terrible at looking carefully sometimes!

I am having a problem accessing the GUI through Safari. It gets stuck on this connecting page and won’t progress to the login screen. I believe this is an issue with Safari’s cache and TrueNAS. Works without this issue in Firefox or Chrome and once I clear the cache for Safari it loads just fine no issues. Then a few hours of load ups later and back to the connection problem. Clear cache, works fine again. Is there a known issue or fix for this? I’d love to not have to clear my browser cache every time I want to log in to my TrueNAS using my preferred (for now) browser.

Thanks in advance!

I use Safari exclusively and I do not have the problems you describe.

Have you checked the browser console for possible errors?

Okay I’ll check that out and report back!

Okay - checked with the browser console and it looks like for me it likely is something with the cache? As far as I’m able to understand most aspects load fine but the “current” entry for the page gets hung up and does not get a response. Then when I clear the cache it works fine and gets a response showing (I believe) the conversion/response of my HTTPS to WebSocket. All the “AI Chatbots” like ChatGPT and Claude keep telling me I need to disable HTTP/2 in TrueNAS and that would likely fix my error - though I’m hesitant to do so because 1) I don’t trust AI chatbots and 2) This feels like a Safari issue so i’m wary to mess with my TrueNAS system.

I also have issues in safari from time to time. Not to the point of no access at all, though.

At least I’m not alone? - Man I just can’t crack this one. It’s every login really - I have to manually clear the cache to get it to access the admin login page. Otherwise it just gets hung up. Accessing on another browser, or in a Private window works just fine - but it’s just annoying I can’t click on my bookmark in my usual workflow and open up my GUI! Happy to try any fixes people can think or or provide more info if it would help…

I don’t see this issue in safari and haven’t had to make any of the AI-hallucinated configuration changes. What version of MacOS / Safari is this?

I’m on the most current stable/released versions I can get - but this also occurs on my iPhone when using Safari:

2021 Macbook Pro M1 Pro Chip: MacOS Tahoe 26.1, Safari Version 26.1 (21622.2.11.11.9)
iPhone 14 Pro Max: iOS 26.1, Safari (whatever comes with my iOS)

I can’t figure for the life of me why this would be happening when there’s no issue with other browsers.

Does your Mac have only a single active network interface? Does your NAS have only a single active network interface? Do both of the devices share the same network or is there any kind of router/firewall/NAT inbetween?

Both Mac and NAS have only a single network interface. The NAS is configured to be static/fixed network interface and reserves three IP addresses - one that I use for the NAS and then the others are for binding to apps. Both devices are located on my primary network, so same subnet, same router/gateway, no NAT or Firewall between the devices. I do have Firewall rules set up segmenting my network (Primary VLAN, IoT VLAN) - but these shouldn’t be at issue here since both the NAS and the Laptop are on the Primary network VLAN and that network has the “keys to the kingdom” anyway and can talk to or interact with all other VLANS and WAN, etc.

It’s really got me scratching my head!

I’m seeing the same problem on 3 x TrueNAS scale boxes at 2 locations from 2 x Macs and an iPhone.

On the Macs I can get things going again by clicking shift reload.

Private Browsing tab has been another good fix - still frustrating but I guess good enough for a workaround if I want Safari

I am having the same issue since updating to 25.0.4 versions. Clearing the cache DOES NOT fix the issue. I have to hard reload the page 3 or 4 times for it to work. Nothing has changed in my setup for Safari, this is a 25.x issue.

Same issue here.

@JoshBurg17 Thank you for the tip!
