error after changing the ip address

[flxxxxddd]

Hi, I changed the IP in the apk file, according to the instructions, but now the application is not installed, it gives an error:

adb: failed to install C:\Users\vad1m\Downloads\com.projectbsds.v41150.apk: Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES: Failed to collect certificates from /data/app/vmdl1166510165.tmp/base.apk: META-INF/APKEASYT.SF indicates /data/app/vmdl1166510165.tmp/base.apk is signed using APK Signature Scheme v2, but no such signature was found. Signature stripped?]

what needs to be done to fix it?

Use apkeasytool
