Hi,

I update from 2.12 up to 2.15 and cannot connect MT4


I update plugin from install. EA have version 2.06 and dll 1.15

account number and password I wrote correct ( double check )

Did you update and recompile the MT4 Expert Advisor too?

Per the release notes: "The MT4/MT5 bridge was changed in 2.15. Re-install the bridge and re-compile the Zorro EA."

The new bridge is probably not the problem. But for some reason, people often succeed installing the bridge the first time, but fail the second time. Maybe they forgot to compile the EA or did not find the right folder. If you find out what it was in your case, please let us know.

For the record, it works for me.

When in doubt, delete the MT4 EA and start over.

Ok,

after clear install MT4 bridge work. Problem is only if upgrade from 1.96

Hi. I have the same problem. I have the MT4 build 1170. Does anyway has the Zorro 2.15 working with MT4 1170? I checked the dll in the Library folder and it is old (from 2017). Is that correct?
Thank you so much for helping!

If you read the release notes, you will find that "The MT4/MT5 bridge was changed in 2.15. Re-install the bridge and re-compile the Zorro EA."
