Service Bulletin 20200205 Telegram BOT

Service Bulletin - Telegram now requires the TLSv1.2 cryptographic protocol, breaking compatibility on Java 6 and Java 7 virtual machines

As of Wednesday, Feb. 5, 2020, the Telegram BOT service only accepts connections from clients using version 1.2 of the TLS cryptographic protocol, breaking compatibility of the Telegram HSYCO I/O Server when running on old Java 6 and Java 7 virtual machines.

Release Date

February 5, 2020

Affected Platforms

• Any HSYCO Server running on old Java 6 and Java 7 virtual machines

Description

Because TLSv1.2 is not supported on Java 6 and is not the default TLS version on Java 7, the Telegram I/O Server, when HSYCO is running on Java 6 or Java 7, will fail to connect to the Telegram BOT server.

Resolution

Upgrade to Java 8, if possible.
