Unable to pick up the quest: "The Art of the Armorsmith"

My character is level 60 and currently has Blacksmithing level of 274. I am playing World of Warcraft Classic - 20th Anniversary on the Nightslayer Realm (v1.15.5.58555)

I have completed the armor smithing quest chain through Tanaris, and have currently crafted the following items:
* 4x Ornate Mithril Helmets
* 2x Ornate Mithril Boots
* 1x Ornate Mithril Breast Plate

I also have the “Glimmering Mithril Insignia” in my bags, signaling that I have completed the “Did you Lose this?” Quest chain in Tanaris.

When I am in Ironforge, I am able to speak with Bengus Deepforge at the great forge and declare I want to become an armorsmith. He then directs me to Grumnus Steelshaper.

However, Grumnus Steelshaper will NOT enable the quest “The Art of the Armorsmith”.

I have already dropped smithing once already to try to “Reset” this quest. I also submitted a ticket (US102990160) and was advised to reset my user interface by following the steps here: https://us.battle.net/support/en/article/000007549.

After completing these instructions, and logging into the game with no addons enabled, I still cannot pick up this quest. The GM in my ticket said “I’ve checked things from my end, and it seems that everything looks normal from our side.”, and suggested I submit this bug report to troubleshoot the issue further.

Thanks for your help.

I am experiencing the same thing on the anniversary server of Dreamscythe.

im having the same issue right now did you ever figure out what the issuer was

I can not get the quest from Steelshaper…he tells me he will train me and that is that. Any ideas anyone please?
