TLS 1.0 and 1.1 are now officially unsupported in all products of HappyFox including HappyFox Helpdesk and HappyFox Chat. On Aug 10 2020, we removed support for TLS 1.0 and TLS 1.1 protocols from our systems. TLS 1.2+ will be the supported TLS version going forward. 

Reason for change:

TLS 1.0 and TLS 1.1 are very old standards having severe security vulnerabilities. Widely used web browsers like Chrome, Safari, Firefox and MS browsers have already started dropping support for TLS 1.0 and 1.1 since January 2020.

Impact:

From August 10, 2020, users will face the following in HappyFox Helpdesk and Chat.

1. Users will not be able to access Helpdesk using very old web browsers that don’t support TLS 1.2.

2. Clients using HappyFox Helpdesk developer API or HappyFox Chat developer API will get failure response if they use old HTTP libraries which in-turn uses TLS 1.0 or TLS 1.1 version to access HTTPS urls.

3. Agents/staff using official iOS apps from iOS 4 or lesser OS version (or) those who are using official Android apps from Android v5.0 (Lollipop) or lesser OS version, will not be able to see/update data. 

Note - Incoming/Outgoing emails in Helpdesk/Chat won’t be affected by this change.

Actions required:

To prevent any disruption in accessing HappyFox Helpdesk and Chat post the set deadline (August 10, 2020), users should do the following.

1. Users need to upgrade their web browser to one of its latest stable versions that support TLS 1.2. IE11+, Edge 12+, Chrome 29+, Firefox 27+, Safari 7+ have support for TLS 1.2. Users can use one of these browsers with the specified versions.

2. API consumers of Helpdesk developer API or Chat developer API should upgrade their HTTP clients/libraries/network-stack to use TLS 1.2 to make requests. If your network stack uses OpenSSL, you can check if OpenSSL 1.0.1+ is used as TLS 1.2 version support was introduced from this version onwards.

3. If you are using our official mobile apps, 

   1. iOS apps - upgrade iOS to iOS 5 or greater.

   2. Android apps - upgrade Android OS to version 5 (Lollipop) or greater.
