failure to load secure web page on web site only.

I have a client who has three user's who without any changes last week started to get the error where when they try to logon to a secure web site they get the error attached,
four other users have no issue with this web site. works fine, whats more strange they have a laptop where two of the user have there login account an it won't work on the laptop either on there user name but works fine on the laptop when logged as others, the laptop gives the same error in or out the office.
there is only on web site with this issue they have no trouble logging on to a number of others, and up to a week ago had no issues with this one.

get the error attached

Did you attach a file? It's not listed

Do you have a screenshot? or is that what you intended to attach?
David Favor

As kenfcamp mentioned, your attachment failed to attach.

And here's my guess.

1) TLSv1.0 + TLSv1.1 have both been deprecated.

2) Most sites now only support TLSv1.2 + above.

3) This means any old OS or browser which only support up to TLSv1.1 will fail with various security related messages.

4) Fix: Install latest Chrome or Firefox + retest. If problem clears, then #3 is the problem, which means your user will have to upgrade their OS or use the recent Chrome or Firefox browser.

Hi,

Try clearing all cookies for that website and retry the login.

Additionally, it could also be a stale browser cache. If so (clearing the cache and browsing history should resolve the issue)

But without knowing exactly what the error is, all we can do is guess

It looks like the browser isn't being redirected properly

The URL being accessed is - user.transact-online.co.uk . Try adding "https://" in front of "user"

https://user.transact-online.co.uk/

It works for me. Maybe try a tracert because at the end I get a time out


David Favor

https://user.transact-online.co.uk/ - Site URL for testing, extracted from .pdf file above.

The error from the .pdf file seems to show the problem I described in my previous comment.

Going one step further...

https://www.ssllabs.com/ssltest/analyze.html?d=user.transact-online.co.uk shows same as my comment.

This site only support TLSv1.2 + TLSv1.3, so devices supporting older protocols will first connect, the immediately receive the ERR_CONNECTION_CLOSED error from your .pdf file attachment.

Your debugging focus will likely be SSL/TLS support of devices with problems... finding some way to update their local SSL/TLS stack.

hi guys
Right
I went into the internet options and unticked TLS 1.0 1.1
I am using  FireFox version 7.3 64 bit , Google chrome is 80.0.3987.100
also tried the new MS  Edge

still no joy

ran the ssllabs report same has above seemed to give the expected results

some more info which may show a twist, this user is an Azure user, if I login the users local user account it wont work in chrome a first but if you run edge and go to transact login page which works the switch to chrome it will the work on the transact login page, while MS Edge is open, shut MS Edge, then shut and reopen Chrome, then chrome again fails. to open transact use login page.
this one a simple ?
