I made OpenVPN settings on the mikrotik RB750 and everything worked fine. but for some reason I also needed to configure the SSTP protocol at the same time. after setting it up, most shared printers and shared folders between computers on the LAN network crashed. so that the prints sent were randomly printed or the shared folder was opened. most systems could not find shared printers, so the files sent for printing remained in the system stack and the printer was offline. folders shared between systems were also unavailable. after the ping printer, usually a reply would come in and then a few Requested time out message was shown.
After two days of searching across the internal network (at first I thought the systems were infected with the virus) I realized that by disabling any of the mikrotik WAN or LAN interfaces, things were back to normal. I came to the conclusion that the problem is in the Mikrotik settings. but I did not find anything in search of the problem. Please help me solve the problem.
The VPNs alone can not cause all these problems unless other configurations took place as well…
But i dont see how someone could help you without seeing any of your configuration…

What if you disable the VPNs ? Problem continues ?
Turning off VPNs also didn’t solve the problem. only by disabling one of the WAN or LAN interfaces would the problem be resolved. I also upgraded the software version to the latest RouterOS version 6.46.1. the settings for both VPNs are as follows:
