Correct. From Wikipedia [1] "On 2 September 2022, the company announced that natural gas supplies via the Nord Stream 1 pipeline would remain shut off indefinitely until [...] compressor station [...] was fixed [...]. Gazprom justified this by claiming that European Union sanctions against Russia had resulted in technical problems".

From CNN Business [2] "On Friday [September 2 2022], shortly after the G7 announcement [of the oil price cap], Russian state energy giant Gazprom said it would not resume deliveries through the Nord Stream 1 pipeline on Saturday as planned."

On 26 September 2022, NS1 and NS2 pipelines were damaged ending any possibility of Russia using them for political pressure or profit.

My understanding is a bit different. Gazprom and or the Nord Stream operator insisted on fulfilling its contractual obligations for delivery but the situation became overly complicated for the reception of payment and some foreign to be repaired turbines were stuck in Canada or Germany because of sanctions against Russia. Then boom.

That was in response to the EU sanctions, if I recall correctly.
