Evidence

I found no Press TV article itself, because my search allowance ran out. Other outlets corroborate the substance. CBS News live updates reported that Iranian and Russian officials spoke on a Tuesday about how to counter the US "Task Force Iron Gate" plan, which targets overland trade into Iran and Caspian Sea trade. CBS quoted Iran's Deputy Foreign Minister Kazem Gharibabadi on X saying they discussed the Caspian Sea, how to counter unilateral US actions, and the Iron Gate plan. He also said Tehran and Moscow stress the need for coordination against common threats. Kyiv Post, citing ISW/CTP, reported that Russia and Iran are coordinating to counter the US operation, and that CENTCOM created the task force on Nov. 7. The Jerusalem Post and Webull also reported the US move to extend measures to the Caspian. I found no Reuters, AFP, Bellingcat or EUvsDisinfo fact-check of this claim. The source reports coordination and discussion. I did not confirm that the two governments issued a formal "joint warning", or the exact Press TV wording.
