Cannot login after recent update

[SamadSaxion]

I cannot login to Source Tree using atlassian account after updating inside from source tree, It keeps saying "Having trouble with Identity Provider, Please try again".

I have tried "Three" different browser
- Comodo Dragon 79.0.3945.79 (32-bit)

. the url changes to:
http://localhost:34106/?state=authenticated&code=75SQSvbVEjKKzT6CJa

.In source tree, 'next' button is turned grey
.nothing happens after clicking on 'bitbucket' logo

.clicking on "create one for free" opens up new page:
https://bitbucket.org/dashboard/overview ( where I can see my repos, wow!)

- Firefox 72.0.1 (64-bit)

"Having trouble with Identity Provider, Please try again"

- Firefox 56.0 (64-bit)

"Having trouble with Identity Provider, Please try again"

I am using windows 7 SP1

I am feeling now that I should not have press the update button, before that everything was working properly.....

Similar experience when trying to add a new remote with sourcetree

Had same experience upgrading to Sourcetree 3.3.7 on windows 10 behind corporate firewall.

Url shows state=authenticated message as above.

Workaround was to install Sourcetree 3.3.6 and then everything worked.
