I do have a weird situation in my group of EWON users. At the beginning of this year we updated the eCatcher from 6.9.0 to 6.10.0. Since this update we have issues with the conneciton to the Ewons.
It is randomly changing to another person/laptop in the office.
To explain this better:
We have a “pro Account” with about 5 users randomly using max. 3 connections at the same time.
We are all able to enter the account and we can all etablish a VPN tunnel to our EWONS without any error message, but only one of us is able to ping the PLC and HMIs on the other side of the connection. This is a real problem as this is changing randomly throughout the day.
This is what we already found out:
1.) First user of the day can work without any issue
2.) All others have the same issue → VPN tunnel seems to be OK but nothing can be really reach. Even not the webserver of the ewon itself.
3.) Talk2Mconnection checker says that erverything seems to be ok
4.) We have checked the Ewon-logfile and found out that the added route has not been deleted after the first connection has been cancled → so each new connection is adding a second route in the routing table which is for sure not correct too.
5.) We have tested this with several different internet connections and with/without firewalls. → same thing
6.) Antivirus software has also been deactivated fully
7.) we have updated the driver for the TAP adapter → this has occured another issue
8.) we have changed back to 6.9.0 → it has worked for one connection but now it is even not working anymore with 6.9.0
Now i am not able to support our customers anymore which is really critical as we have about 400 EWONs out there…
Honestly i am not even sure if the fault is on your side but maybe you have any other idea where i can look at.
Thanks in advance.
