ArgumentOutOfRangeExceptionThe value is outside the supported range.
Remarks
Specify a whole number of hours from one hour through 30 days, inclusive. The value applies when creating a tunnel and when updating an existing tunnel. When null, no expiration override is sent: new tunnels use the service default and existing tunnels retain their configured expiration period. This is an idle expiration period, not a maximum hosting duration or an access-token lifetime.
