Webaccess logs in but no browser page is loaded

Web Client

Updated May 7, 2020

asked on March 30, 2020

I upgraded our system from 10.2 to 10.4.2 and it created an issue with both webaccess and mobile. Both Web Access and Mobile are running on a machine separate from the LFS machine. This was working fine until the upgrade to 10.4.2 and there were no errors reported during the upgrade process.

Webaccess: (I suspect mobile is related to the same issue)
I can navigate to the website, it presents a logon screen as normal. I try to log on and the screen flashes but the logon panel doesn't go away and one of two things occurs. 1. Mostly the Laserfiche webaccess interface behind the login panel just stays white. On the Laserfiche server (different machine) the admin console thinks I am logged in. (Occasionally I get the Laserfiche panel to actually show the root folders, but the mouse spinner just spins.

I have reloaded web access on the web server after removing it completely and changing the name of the programfiles/Laserfiche/web access directory so it looks like a clean install. Same behaviour. I also did a repair on the LFS service on the laserfiche server. Also no luck.
I also changed from Laserfiche authentication to windows authentication in web access and get the same behavior.

Mobile: was also working fine but not when I try to log into the repository I get an "Unknown Error" message. I suspect it is related to the same issue.

Any ideas?

Apparently Laserfiche is defaulting to using secure cookies, even though we are not using SSL for this. Turns out there is a procedure in web.config to not require that. When I removed that setting, Web access started working. I guess they changed the default setting between 10.2 and 10.4.2 and when I upgraded it just broke it.

By default, Laserfiche Web Client 10.4.2 Update 1 is configured to require secure cookies. By extension, this requires configuring the web client for SSL/TLS. If you must continue to use HTTP communication, you can manually modify the web client web.config file to turn off secure cookies.

To turn off secure cookies

Open the web client web.config file in a text editor. By default, the file is located at: C:\Program Files\Laserfiche\Web Access\Web Files\web.config.
Locate the following line within the <system.web> block around line 23:
```
<httpCookies requireSSL="true"/>
```
Delete the line.
Save the change to web.config.

Be aware that if you turn off secure cookies and you are using Google Chrome version 80 or later, you may not be able to sign out of the web client or authenticate when the web client is embedded in an iframe.

My first guess is that the sites are not using https. Browsers are evolving to encourage https, and there can be impaired functionality without it. There's more information in https://support.laserfiche.com/kb/1014094/additional-configuration-for-chrome-80 .
