Portal works in EI and Chrome, but not in Firefox?

MarkHotz

I have always been confused by this, but have never really sought an explanation. Would anyone out there have an idea of why I can publish map services to Portal and can then visualize and interact with those map products using EI and Chrome, but when I use Firefox only my basemap loads, and none of my layers?

At first I thought it was my machine, so I didn't think anything of it, but we are only just implementing our web based GIS and now we are getting more interest and users. However, it turns out that it's not just my machine as I set up a co-worker to experiment with our new web application and he too was unable to load any of the layers using Firefox, but with EI and Chrome it was fine.

Is there a known problem with Firefox? I would find this odd because with ArcGIS Online Firefox works best in our office...and Chrome was the browser with issues.

Thanks

Mark,

Could you capture the network traffic (i.e. run Developer Tools) in Firefox to see what is going on there? Additionally, what type of certificate are you using on your Portal (i.e. Self-Signed, Domain, CA)? Lastly, what version of Firefox and Portal are you working with?

Thanks!

Andrew

Andrew: Thanks for the response. I haven't run any Developer tools in Firefox (I would need a pointer on how to try that, but I can try launching them to see what happens - I'm not a developer so I have never had a reason to use those). I never thought about the certificate though. Our IT department took care of that, so that might be a good place for me to start. I will certainly initiate that conversation with them right now and reply again.

The version of of Portal (and ArcGIS for Server) is 4.1. We only just implemented everything is July. The version of Firefox I'm running is 48.0.

Thanks for the information. To run developer tools in Firefox, click on the three horizontal bars to the right of the Address bar. There you'll see a drop-down of options, with one option for 'Developer.' If you click on that, another list will pop-up -- when that happens, can you click the option for 'Web Console'? That should open up "Developer tools." When it is open, can you then click on the 'Network' tab and then try browsing to your Portal? If there are any errors, they will show up here (hopefully!). Thanks!

Cheers,

Andrew

Andrew: I got the developer tools to function and it does provide a lot of information. My issue, it seems, is restricted to the local server. I have a base map (satellite image) that is being accessed through ArcGIS Online, and this seems to work well. Anything on our local server is being blocked (I'm guessing); hence, anything on Portal and ArcGIS for Server is not being accessed by Firefox.

Our IT department did say that certificates could be an issue, but they wouldn't elaborate more than that at the moment. I'm waiting for our IT manager to return from vacation (should be today or tomorrow) and I can talk to him more about certificates as he's the one who acquired what we're using here for Portal.

The first error message I came across before reviewing the Network status was:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://www.google.com/_/og/promos/z. (Reason: CORS header 'Access-Control-Allow-Origin' missing).

So nothing from Portal, our geodatabase or Map Services are being accessed when using Firefox. I also cannot see this being a huge problem...it almost sounds like there is one check-box or one configuration setting that was missed or has yet to be properly set.

Thanks again
