@djouallah have you tried another os to read with?

(btw a normal azure read works fine, manually verified that)

[ion-elgreco]

@djouallah I suggest you try to compile of each of these branches and report back if it resolves the connection issue:

• https://github.com/ion-elgreco/delta-rs/tree/fix/rustls
• https://github.com/ion-elgreco/delta-rs/tree/fix/use-native-tls-vendored

windows works fine with onelake

[ion-elgreco]

Ok then it's related to the SSL handshakes. Please compile both of these branches I've shared above and let me know the results of each, then I can narrow down the fix

[ion-elgreco]

@djouallah can you check the latest release out please
