iOS AnyConnect app bug in version 5.1.11347

[Hostera]

1- Problem in switching tcp / udp
2- After locking the device (iphone & Ipad) the connection is lost and the reconnect enters the loop mode, especially in DTLS
3- OnDemand mode exacerbates this issue
This has nothing to do with updated versions of the operating system
This is only observed in the new version of Cisco.
After 3 weeks, there is still no update for this issue.

It sounds like a known issue with the latest Cisco version affecting TCP/UDP switching and DTLS stability, especially when devices are locked. As a workaround, try disabling OnDemand mode and manually reconnecting this can prevent the looping. You can also switch the protocol manually to TCP for a more stable connection until Cisco releases a patch. Checking your AnyConnect settings for “Allow background refresh” might also help keep the session alive.
