Tried custom upgrade (EAP653v1_1.3.6_[20260306-rel14246]_up_signed.bin) with the same results

The link below has firmware versions 1.3.6 and 1.3.7 for a CA model, nothing for the US. Can I use it?

Upgrade fails from 1.3.5 to 1.3.6 with the following message: Tried rebooting device prior to starting upgrade, dropped all clients but it didn't fix the issue

@Tedd404 As I've mentioned, the other side is managed by another team and ofcourse parameters are known and negotiated, however you still don't have a way to validate it. Debug log should tell...

@Tedd404 comparing both sides is not an option when two devices belong to a different organizations and managed by a different administrators. Debug log is essential so one can pinpoint the problem.

I have trouble establishing IKEv2 VPN with with another client. I suspect it could be proposal miss match in Phase 1 or Phase 2. How can I get debug logs? Device is managed by oc200 controller.
