Authentication error

Deleted all copies of SU 2015 and 2016, reloaded SU 2016 and got the the same “Authentication Error!” again this am. jrt

See my steps above. Something’s cached, and you must clear it.

Try running Sketchup as administrator if you’re a Windows user. Deleting the cookiejar didn’t work for me, but running as admin cleared it right up.

.I initially had this problem after downloading and installing the 2016 ver. I deleted that and installed an older ver. which l worked last pm after I cleared up a problem of numerous load errors with the help SU community members. When I reloaded 2016 ver. the problem came right back.
I deleted all copies of SU searched my hard drive for any remaining SU files plus cookiejar.xml and session.dat files I have now loaded an older copy (2014) from the SU website and it is now working fine, and I can now use SU warehouse. 2015, 2014 ver. have worked, 2016 seems to cause problems but I have loaded and deleted so much stuff its hard really say. Thanks for the help. jrt

Note that each version has it’s own cookiejar.xml and session.dat. If you’re having 2016 problems, confirm that you deleted the 2016 files.

here is the solution the pro support came up with :

We have been preforming some maintenance to our login system and are currently working on a fix for this bug. So far the most successful solution has been to log of your Google account out by selecting the icon at the bottom right side of the SketchUp drawing window (see attached photo). Once you are logged out, log back in and then try to access the Extension or 3D Warehouse again and it should allow you to log into your account.

this worked to resolve issue immediately on all copies and versions


same thing!!! for about last month

You’re on Mac? …

PC, win7 , but last time I have that "Authentication Error " a lot …

OK, so did you try what I wrote above: removing cookiejar.xml and session.dat?

fortunately, for now works ;but thx for that hack ;]

I get the same error almost every time I switch to a different wifi. Same solution as mentioned above by @Rich_E : sign out and back in through the sign in button at the bottom left of the SU screen. Works every time.
(Win 8)

This worked immediately, thanks. FYI logs you out of all of google; not a problem but unexpected.

This worked for me so far… thanks.

Same problem. Tried everything listed above (deleting file etc) didn’t help. It turns to “Authentication Error !” the minute I open sign in window, can’t even check if I was signed in before.

Yup, back on this treadmill again, cannot get into my wherehouse account or sign into the SU program itself. Everytime I try to sign in i get the "heres our Shiny new login page and when i click to login it gives ‘authentication error’ message. Doesn’t happen when I log into trimble, or into my SU 2016 program. only happens when I try to log into the SU 2015 program, or the wherehouse through SU 2015 or the EXT wherehouse through the SU2015, which really sucks as that is the one I primarily use.

Just one thing, check the accuracy of your links, as you have spelled warehouse incorrectly in this post. It only takes one letter.

Remove files listed above again and clear IE cache. Again.

I don’t hand type the links…thanks for the spell check tho

Hi Barry,
I’ve deleted the cookie jar.xml and don’t get the session.dat file but it didn’t work. where is the IE cache? I didn’t have to do that one before. Whats really odd is it worked yesterday morning and quit by the night. also not doing it on my SU 2016 pro, this is only happening on my SU 2015 make, does it have something to do with the make version?
thanks again for all your help
