Unable to Connect to Portal. (kCFErrorDomainCFNetwork error 301.)

APaulsen — Thu, 26 Sep 2019 12:24:27 GMT

We supposedly have all our ports open for mobile devices to connect to our Portal, though when I simply try connecting through the Explorer app on iOS (Apple device), I get this error. Anyone else have this error or know how to resolve it? Is it our server and security or the iPad/ iPhone??

Hi Andrew,

What version of Portal are you using? Is it configured with a CA certificate signed by Comodo? This is my best guess, at first glance:

Hm, a 301 HTTP code means it's redirecting, but that may be different from IOS exception codes. A quick search online returns a list of ErrorDomainCFNetwork exceptions, and it seems like 301 may be bad credentials? Not a developer so this is a pretty big leap:

10.7.1

It works through the browser (Safari) though not through the app. We also have it where our Portal uses Windows authentication errors out before prompting for user name and password.

I should also add that I can get into our Portal through a browser, though once I click on a web app there is nothing there.

This happened to my boss after she updated her iPhone. To verify, I updated my phone today to 13.1.2 (was on 12.4.something) and I get this same error now, too. It was connecting without issue before the upgrade.

Isn't this bug a resolved ArcGIS Online Bug? Would it also apply to Portal?

I'm also on 10.7.1, am experiencing this issue, and as I mentioned in my other comment on this thread, this issue only started occurring when we updated our iOS to 13.1.2, which makes it seem like an Explorer app compatibility issue, not a server-side cert issue.

Is ESRI going to respond on this. We have same problem and all field workers using Explorer on iPad get this error now. This is a major problem.

please advise

I called a couple days after my posts above and they were already aware of this issue; an Esri response on here to confirm the bug would've been nice.

Here's the email response I got from technical support w/ BUG # so you can track progress:

As discussed over the phone, you are unable to sign into the Explorer for ArcGIS app on your iPhone with your Portal for ArcGIS (IWA) credentials. The error message is, kCFErrorDomainCFNetwork error 301.

You are encountering a high priority defect which is occurring after the iOS update to version 13. The only workarounds are to disable IWA on Portal or use an iOS device with version 12.0.x.

I have attached your case to the below defect. You can track the status of the defect in your MyEsri account.

BUG-000125896 - After updating to iOS 13, Explorer for ArcGIS is unable to login to Portals configured with Integrated Windows Authentication(IWA) with the error kCFErrorDomainCFNetwork error 301

Hopefully "high priority" means they're going to make an emergency release rather than wait to perfect the update that they claimed would come this summer.

I am in the same boat as you, our field workers depend on this software and iOS13 is needed by our IT department for security updates. When are you going to resolve this issue esri? this is causing a major loss of service for our users!

I have contacted tech support as well and they have this logged as a bug, iOS13 was a PUBLIC beta in June, why was this software not ready for the roll out?

I am suffering the same IWA credential issues with Explorer for ArcGIS and Workforce for ArcGIS after iOS 13+ updates. According to ESRI support this known "high-priority" bug fix won’t be rolled by ESRI/Apple until Mid-December. I assume the significant time delay must have something to do with Apple Store validation/QA? Nonetheless, this bug will definitely impact production applications at my site.

There is a beta hotfix for BUG-000125896 (After updating to iOS 13, Explorer for ArcGIS is unable to login to Portals configured with Integrated Windows Authentication (IWA) with the error kCFErrorDomainCFNetwork error 301). The beta version is a separate install and it will not replace the existing Explorer app on your device.

If you are interested in accessing the beta, here is the link:
https://testflight.apple.com/join/qFpZXwiV

After you open the link on the device, you need to download Testflight which is an app for testing beta versions, then you can install the beta version of Explorer.

We got the same problem when some of our field workers decided to update iOS, even when our IT department suggested to wait. We are using ArcGIS Enterprise and a Portal hosted internally. We can't wait months for a fix, but luckily we found a workaround. It's not very elegant, but it works for now.

In Explorer for ArcGIS, try to log to your portal directly, rather than through the web adaptor.

Normally, we would connect through a url such as: https://serverAlias.domain.com/portal but then the OS authentication fails.

On the other hand, we tried to connect directly to the portal through a url such as: https://RealServerName.domain.com:7443/arcgis. If it works, you get redirected to a login form for the portal similar to the one on a web browser. You need to use you windows credentials (domain\username + Windows password).

ArcGIS Enterprise 10.6.1

Explorer for ArcGIS 18.1.2 (version 2379)

My coworker and I have also found this issue in Collector when trying to log into ArcGIS Enterprise on iOS 13.x

Hi! I got an invitation for the beta test of Explore 19.1.0 and tested for this problem. It fixed! I was able to connect to our portal with iOS 13.x.

Re: Unable to Connect to Portal. (kCFErrorDomainCFNetwork error 301.)

APaulsen — Fri, 13 Dec 2019 18:53:30 GMT

Yuko,

Do you know when they will release Explorer 19.1.0?

Re: Unable to Connect to Portal. (kCFErrorDomainCFNetwork error 301.)

YukoYokozawa — Fri, 13 Dec 2019 18:58:20 GMT

I don't know the exact date, but when I sent the feedback they replied saying "we should go final later in December".

Re: Unable to Connect to Portal. (kCFErrorDomainCFNetwork error 301.)

APaulsen — Fri, 13 Dec 2019 19:03:19 GMT

10-4. Thanks for the update. Esri bugs and whatnot can be a pain.

YukoYokozawa — Fri, 13 Dec 2019 19:19:47 GMT

I agree!!!

Re: Unable to Connect to Portal. (kCFErrorDomainCFNetwork error 301.)

MikeLong — Thu, 02 Jan 2020 20:00:05 GMT

This appears to be resolved in the latest release. Version 19.1.0 build 2614.

This issue may be fixed for Explorer, but not for ArcGIS Workforce iOS client. The current iOS Workforce version is still 17.0.1. Its release Date is December 15, 2017.
