Hi, should the ziti-edge-tunnel 1.9.x to be compatible with controller version 1.6.9? I have experienced problems with ziti-edge-tunnel 1.9.x version, 1.7.12 works. When I upgrade ziti-edge-tunnel to 1.9.x version on “source” side of tunnel, its works some times like 12-13hours (I don’t have exact time) and after it doesn’t pass traffic anymore and on log it repeat following. This happened on both 1.9.3 and 1.9.5 version on couple of servers. When I downgraded back to 1.7.12 then no problems. Also 1.9.x version works on “receiver” side. I have only 1 controller and 4 routers, all on version 1.6.9. ```auto Nov 23 07:33:16 rproxy ziti-edge-tunnel[792]: (792)[81104.949] ERROR ziti-sdk:ziti.c:1568 update_identity_data() ztx[1] failed to get identity_data: no api session token set for ziti_controller[UNAUTHORIZED] Nov 23 07:33:16 rproxy ziti-edge-tunnel[792]: (792)[81104.949] WARN ziti-sdk:ziti.c:1570 update_identity_data() ztx[1] api session is no longer valid.

Bonjour @guenne, did you intend to reply on this post? If you would like help from the community, you probably should make your own, separate post ---

> [@timnis](#): > > should the ziti-edge-tunnel 1.9.x to be compatible with controller version 1.6.9? I would expect it to be, yes. It sounds like something is happening that shouldn't be. There have been a few issues around oidc lately, I don't konw exact what but it might be worthwhile to try the latest controller if you can. I'll mention this to other colleagues to see if there's anthing obvious in that log snippet. ---

Thanks @TheLumberjack. This is production, so I think I wait new release 😃 I have test environment also but haven’t noticed this problem there.
