Dear Psi4 community,
I employed following input to perform SAPT0 for platinum complex with iodine derivative but the error message “Failed to converge” is returned in console. Futhermore, I have error in output file

Replacing platinum with palladium gives the correct result. expanding disk storage and RAM didn’t help. It should be noted that this happens when using def2-tzvp
Please let me know what is the solution. Many thanks for your kindly attention.
Best regards
