From the article you posted:

"The talks were jolted by statements from Trump, who, from thousands of miles away, fired off comments that offended the Iranians.

Iranian state media said talks had paused after the “publication of an insulting message by the U.S. President.” The negotiations later continued."

So it did in fact happen, but despite the geriatric manchild torpedoing his own begged for peace negotiations the adults in the room recovered.
