Nice one Alain!

Initially this fix did not work. I already had a network name.

I reset my location and trashed my system config:

Then entered a network name.... voilà! it logs in and syncs :)

Still not working on my MacPro but works fine on my MacBook Air. Both have always had computer names so there's something else going on here. What gives?

Peter,
What's the output of the following command when run from Terminal?

scutil --get ComputerName

Thanks,
Matt

Matt: I'm not at home for the next couple of days. Will try it when I get back. On my MacBook, which works fine, it says "Peter's MacBook Aur" which is what shows in the Sharing panel.

Matt: I tried it on the Mac Pro (which is the one that doesn't work) and it reads "Mac Pro" which is the same as the name in the Sharing panel.

Max,
Are you getting the exact same error message as in the screenshot above?

Do you have any firewall or proxy that might prevent access to https://api.adbecrsl.com or https://ims-na1.adobelogin.com?

Thanks,
Matt

Wukoki,
You are unable to log in and the *exact* same failure message (including the '(attempt to index a nil value)' is appearing?

Do you have any firewall or proxy that might prevent you from accessing https://api.adbecrsl.com or https://ims-na1.adobelogin.com?

Hi Matthew,

no, I get no message at all. I cannot Login using Lightroom, nor directly to the web (lightroom.adobe.com). I cannot login using iPad neither.

I do not have any proxy or firewall.

Wukoki,
Your symptoms sound more like an account issue. Have you talked with Adobe Support yet?

FYI Windows users: i was having the same login problem with windows 8. After updating to Windows 8.1 i was able to log in. So if you are having issues logging in, maybe updating to 8.1 will help you also

I am also having the same exact problem on my Windows 8.1 machine. How do I resolve the problem? I can login fine from my iPad.

One more thing to add to my previous post: my Photoshop CC installation on that same machine can login fine to my Adobe ID, so there is no problem with my computer ́s network settings, like proxies and the like.

Jose,
Photoshop CC and Lightroom currently use slightly different methods and servers in order to log in with your Adobe ID right now so the success of one doesn't guarantee the success of the other. You will want to verify that firewalls and proxies are not blocking access.

When you try to log in you are getting the exact error message in the screenshot above? Does it return immediately with this error message?

Is your connection wired? Or wireless? Does your machine have a computer name that you gave it? Are you running as a logged in user or Guest?

I have about given up trying to log in with Win 7. I have turned my firewall off. Edited the host file as was suggested somewhere. I get the message above minus the nil part. Nothing happens when I hit sign in other than the 4 little blocks going in a circle. The directory where my files are is shared. No problem with the ipad. It signs on just fine.

Any suggestions?

This solution is not working for me. I already have a name in the Computer Name dialogue Box, and the error message I get when trying to sign into LR mobile is missing (attempt to index a nil value).

If you're on Windows or getting the error minus the "(attempt to index a nil value)" part, this solution won't work for you and you should start a different thread. In most cases it's caused by a network failure to connect to the authentication servers, usually cased by a firewall or anti-virus software.

For those on Windows (or Mac too if there are some) who have verified connectivity to https://ims-na1.adobelogin.com and https://api-lr.adbecrsl.com and are still having this issue logging in to Lightroom mobile:

Can you check whether your network connections are using IPv6 only? You should be able to do this by opening a command prompt and typing 'ipconfig.'

Do any of your listed adapters contain a line and value for 'IPv4 Address'?

Thanks,
Matt

I have disabled ipv6 and it still does not work. Ipv4 is only one showing up when I do ipconfig. Disabled ipv6 in Zonealarm and have completely turned off zonealarm (firewall and anti-virus). Simply can not connect to Lightroom mobile.

Richard,
If you are not getting the '(attempt to index nil value)' part in the message on login neither the original solution for OSX or any changes related to ensuring an IPv4 address exists will work as it is a different issue.

What do you get when you attempt to access the two URLs that I mentioned previously?

Thanks,
Matt

As for the 2 url's, nothing happens for the first, just a blank screen in Firefox and the second I get "Nothing to see here. You want the Adobe Revel site instead."

I do not get the nil value part. I am under the understanding that that is only for osx and not win 7.

The results for the two URLs are what I would expect so it's not strictly a connectivity issue.

As for the nil value part, it can occur on both platforms for different reasons. OSX is far more common and the fix for that is above. Windows runs into it far less as it appears to be related to IPv6 only network configurations, but I am hoping those who are on this thread and experiencing it can verify that.

Unfortunately, you are hitting a different login error (without the 'nil value' part) for which we do not currently have any workarounds.

This should be fixed complete in Lightroom CC/Lightroom 6.
