Mapillary Plugin does not log into Mapillary

[miketho16@…]

What steps will reproduce the problem?

1. click "Edit" menu
2. click "preferences"
3. click "display settings" (top tab on left)
4. click "Mappilary" tab (top right)
5. click "login" button
6. Default brower opens to a Mapillary page
7. Log in to Mapillary with mapillary username and password
8. Log in is successful
9. Mapillary page then asks me to "authenticate" (i.e. grant JOSM access to my account)
10. click "authenticate" button
11. a new webpage is displayed whose address is "​http://localhost:8763/?error=invalid_request&error_description=Wrong%20RedirectUri%20provided" (note apparent error message in address)
12. The above webpage displays "Login successful, return to JOSM"
13. alt-tab to return to JOSM
14. click "file" menu
15. click "Upload Pictures" (menu item has Mapillary logo to the left)
16. Message is displayed "go to settings and log into Mapillary before uploading"

What is the expected result?

1. No error message embedded in web address, e.g. not "​http://localhost:8763/?error=invalid_request&error_description=Wrong%20RedirectUri%20provided"
2. After performing the steps above through #15, I am able to upload photos to Mapillary.

What happens instead?

Thanks for reporting, I'm talking with the Mapillary team trying to fix the issue.

[miketho16@…]

Thanks for the quick action. Let me know if you need any additional information.

It should be working now, it was a bug at their side because of a server crash they had.

Tell me if you still have any issue
