Why would SSH authentication suddenly stop working?

Question

I have been sporadically but successfully using BitBucket with SSH authentication for years.  My last successful commit was on 2019-03-21.

On Wednesday of this week, SSH authentication no longer worked despite using the same private key/public key combination used for years.

Has anything changed recently with BitBucket's SSH authentication?  I believe my old SSH key is quite short (1024 bits?).  Was there are recent change deeming 1024 bits as too short?

On the client side, I am using Spring Tool Suite (Eclipse) version: 3.9.4.RELEASE with EGit 4.11.0

Yes, I could create a new key pair.  There are some challenges related to changing keys that I am hoping to avoid.

Thanks.

Although I am embarrassed to post this, I hope it will help someone else down the road.

This problem has been solved; I had simply been using a slightly incorrect passphrase.

Because the passphrase I was using was close to the correct passphrase, I had convinced myself I was using correct passphrase.
