Hiring on Hold After Receiving an Offer

I recently received a written offer for a position I was very excited about. After reviewing the offer, I had a few points to negotiate, such as the start date and some questions regarding the bonus. My references were checked and confirmed, and I was told I would receive an updated offer soon. I was also advised not to notify my current employer until all the terms of the offer were finalized.

However, after a few weeks—during which the initial start date arrived—I followed up and learned that, due to various operational reasons, they needed to pause the hiring process. They expressed disappointment, stating that I was an excellent candidate.

I’m curious if anyone else has experienced something similar. Since I was really enthusiastic about this role, I’m considering reaching out in a few months to inquire about the possibility of resuming the hiring process. I did reply to their email indicating my continued interest for future opportunities. How long should I wait before following up? Has anyone successfully navigated this situation and eventually secured the job?
